I also have been toying around with trying to create a MMO fast action space simulation of my own creation. I have a few ideas on how to limit areas of dense players with game mechanics. I haven't even really started on multiplayer beyond the ability to download modify and upload solar systems though.

I think for some really hard engineering problems like this the best course could be to try and find a 'good enough' approach that will allow a significant ammount of players to interact while limiting the upper bound with a game mechanic to make it feel less artificial.
