This is not so unusual its exactly how the piggy swap worked on cubits. We all had databases on cubist and posted seeds, then looked on each others databases and asked for what we wanted on a central thread. What dave is proposing would be individual treemails to each other. It saves tons on postage. But is hard on the central seed person. Maybe Dave could delegate some of the work.
Seeds only is what I'm thinking, impossible to have plants in winter.
