Assuming this is not a troll post, as a HUGE fan of space simulators this sounds great.
I'd be surprised to see it happen though, spacegames are very expensive to run and make (Thats why egosoft wasnt done an MMO version of their X series of space games, which doesnt all that chadz posted, besides making your own ship - as in the shell, you do get your own parts and some modifications - and it also has perm death, but being a SP game, you just go back to your last 'save')
