I would be interested in the seed exchange. I always have lots of extras and I participate in other seed trade groups.
The logistics of your plan is a bit to grasp, but maybe with an effective accounting system it might not be too hard to keep track.
I don't think you could effectively mail plants this way, there would be too much lag time trying to get everything together and packaged to mail out.
I'm for giving it a try and seeing if it's do-able.
