I s'pose we Outcasts can always summon more invisible fleets to combat. Uhh. Sorry, didn't want to sound sarcastic, but some of us need more than empty space and chat screen.
Our roleplay involves spreading our borders and hunting others.
Now, if we decide to build a base somewhere, we'll have to fulfill bunch of silly requirements anyway. Why not make us work in-game instead?
We would battle a boss for those rare permits and other junk and have fun roleplaying at the same time.
I'm pretty sure these "silly requirements" that you speak of will be in-game tasks as well as forum RP. Its already been stated that these tasks will be a mixture of Trading, Mining and Fighting, there's no reason for a "boss fight".
As for the Outcast RP, you're only as limited as you make yourselves. I think its safe to say you guys are pretty PVP driven faction, I also think its safe to say that because of that you guys are often bored when the server population gets low.
My suggestion, get creative.
We have ships like Light Scout (like that Starcrapper we get when we undock Manhattan for the first time), Medium Scout, Cruise/Thrust Interceptor. Compared to say, FAF they are weaker, no? CI on the other hand stands equal with the fighter classes in pvp but it still has weaker stats. And because of that its price is lower in-game.
Its been proven over and over that no ship is "weaker" than the other. I've had my butt whooped by someone in a scout ship while I was in a FAF, I've killed CI's in a Bomber. The PVP aspect of this mod is based heavily on skill and play style. Making it and MMO type of leveling system would remove that aspect and I assure you a good amount of people would leave knowing that, that freedom had been taken out of the equation. I don't want spend days upon days to work for 60,000,000 Bomber or Superiority fighter. It has nothing to do with strength of the ship, I've lost battles against all kinds of ships, but it has everything to do with my play style which is something that FL has never dictated.
Let's say you just started playing on the server. First two-three hours you spend doing missions to get to level 10. You can now fly a Medium Scout. After you buy it, you take harder missions and spend another three hours getting to level 20. After that you can settle in for a Heavy Scout (level 25) or CI (level 28). FAF would be level 32, Superiority 34 and Multirole 36. Fifteen hours total to get to level 36. Now you can use any combat ship you want with your leveled char since you are "experienced" enough. And that is all leveling you need to do as PvPer/roleplayer. Nothing has changed. Only how you acquire ships.
Again, that is just implimenting too much limitation. I know I'm already "experienced" enough to fly and fight in a Superiority Fighter or a Bomber because those are the ships that I am most relaxed and most efficient in. I don't want to be stuck in a small spec of a ship, zipping around the system at the speed of light because of the time I've spent in game.
Aside from that, I dont see roleplaying surviving in a system like that AT ALL. People would be too preoccupied getting "stronger" to want to interact with anyone other than fighting or defending themselves against/from weaker/stronger people. There's more to RP than the required "Die scum" and the unavoidable PVP battle after that. As it stands right now, FEW people in-game take RP if they even participate in it at all.
What I've meant to say is that bomber is easily accessible to anyone who wants it. Its sole purpose is to destroy a BS. I had a chance to see it in action. Lets say you decide to log in with your unique Liberty Destroyer capship. No fighter can harm you.
With exp system hostile players wouldn't be able to just /bank withdraw money with their freshly made char. They'll either have to exchange their fighter for bomber, or level another character specifically for bomber. Gives you a breathing space. Sounds tedious for bombers? Not if you add another weaker bomber with lower lvl req (to be used against normal purchasable battleships/corvettes, not capship though).
Would they? Quite frankly, I haven't seen enough love for bombers to believe anybody would just make a new character to buy one and blow a person up. Its easier and more cost effective in that situation to simply run. Also the whole concept of a "bombers purpose" might be a bit of a bold suggestion. They're surprisingly effective in a dogfight. And for people like myself who don't like to bullet around the combat zone they're quite nice ships in general. Again, the system you're suggesting would hold people back from using the kind of ship that suits their play style.
Grindable items are faction permits, cosmetic junk and things like advanced thrusters. Basically you are grinding for luxury and customization. People constantly look for special parts, and I don't see them ignoring rp. But yeah I see your point. However you shouldn't expect much from those kind of players anyway. But you want to keep them playing for as long as possible in order to help the server population snowball.
This leveling system (not grinding) is far less tedious than in any other MMO. Your guns and shields are cheap as always. You grind not only for parts but items used in roleplay. Game remains all about the roleplay.
Weren't you talking about leveling up for "better" ships?
Thats a little less of a "cosmetic" and more a necessity if you ask me.
And no...I'd rather have a small community of people who actively interact with one another than bustling 100+ 24/7 pubserver full of people too focused on leveling up to give a damn about universe they're playing in.
Well, I am done explaining. Next time I'll make sure to avoid words like "WoW" and "grind" because it caused you all to interpret my ideas in the worst possible way. 
I think it was more of the "Lets make Freelancer an MMO" concept that got to most of us
