I have been away for some time but the last time I checked here there was talk of starting a scionwood exchange. Has that come to fruition or is it just an idea? For the record, I would love to see a scionwood exchange. What a great way to add additional varities to our (especially fruit) trees...
There's currently a fairly active Yahoo! group devoted to this. I'm on their emails. If you're wanting to start one specifically centered on this site, I'd be in to contribute (although I'm a relative newbie at grafting).
