I like the idea. I see nothing wrong with people forming a group that is in it for there own personal gain role-playing a trader, without the political baggage of a house corporation. Could still work as a group, small convoys etc etc. Maybe even encourage some of the people basically doing this anyway to join up and work in a team setting. Could promote more involvement server side (player interaction) and RP. Why be forced to RP a house corporation. Be like a independant truckers union, you haul freight for varies companies but hold no other obligations to them. Move freight from point A to point B, get paid and move on to next job.
