I must take a lunch as well - so a nice break for all of us from this thinking and pondering.
I concur with Peter, as long as the right members were used from the start there shouldn't be problems, and, as he stated, an odd number to prevent ties, 11, 13, what-have-you, and no more than one rep per company to ensure that they couldn't "gang up" so to speak.
If one decided to step down, or was putting the organization's integrity on the line, said member could be voted out and a new member brought in.
Edit: off to lunch I go, and Peter, they've seen the thread...cause I've been checkin' the "who's online" deal
But I would love to hear some more comments/points brought up. I'm enjoying this discussion.
