Do keep in mind goals (or Endeavors) when creating your characters.  My hope is that the OOC will be a place for players to coordinate with each other in how to successfully complete not only Endeavors for the group (thereby increasing Profit Factor and accumulating treasures) but also in completing personal Endeavors for their characters.  A tit-for-tat system is certainly acceptable whereby you secure the resources of another character (their skills/equipment/influence) to achieve your goals and they can utilize your character's abilities.  Rogue Traders are greedy people afterall and everyone has their own agenda.
