I have traded a few too, with photographers whose work I find intriguing / interesting. It has been a wonderful exchange.
I have also partaken in member organized print exchanges that are blind. That has been fun too, but you have absolutely no clue of what you'll receive, and there is chance of both luck as well as disappointment. Most of the time it turns out well it seems.
What I like about this is that some level of agreeing terms with the photographer that's interested seems possible, and you can even see a scan of the work before it's exchanged. Now that I like.
I am not the world's most experienced printer, but I would certainly be willing to put up prints for trade occasionally.
Great initiative, Jason! And now you can brag about being a moderator too!
