This sounds like great fun. But its important it is planed and done well.
A good ide might be having a meeting with a "diplomate" from every faction.
Maybe not just in space but even Skype or MSN?
I also suggest that we save pilots from (npc)ships that gets killed. So we can transport prisoners during the convoys.
Would be fun to liberate 5000 Hessian pilots wouldnt it?
