Crystal and I were discussing Go Play Peoria, and she suggested the idea of allowing local designers to sell stuff at the minicons. I was mulling this over, when I saw this post by Ron:

Darcy, one of my dreams dating back a couple of years is to see as many Forge Midwests and Nerdlycons and similar things emerge as possible. I guess we could dub them "playcons." They're diametrically opposed to the current big conventions, in that there's no distinction made between publisher and congoer, and no emphasis at all on marketing of future play - rather, it's on playing, period. They could range from smallish local get-togethers that aren't much more than an inclusive game night for a given area (Go Play Peoria is like this, or a grade up from it), to pretty-unique events that are more like the weekend camping thing that Nerdly did, with strong cross-country or even international draw. Forge Midwest is about midway between these two examples..

I would like to see at least some of them include commercial opportunities, as we did a little bit with the last Forge Midwest. Not booths or static exhibitor tables, but more of a front-pocket to front-pocket buying situation for those who decide they might bring some stock.

Great minds obviously think alike.

Now, at this point, I'd want to limit this opportunity to folks who would actually be at the con. I don't want to start a dealer's room or anything; I just want to allow for some of this commercial contact to happen. (I'm not even limiting this to RPGs. If someone produced a boardgame locally, it would have equal time at GPP.)

So, I was hoping to gather some thoughts from folks about this idea. What would be the best way to implement this idea? What are potential pitfalls to this idea? Are there other datapoints out there? I'm aware of the buy/sell at last Forge Midwest, though I'm interested in hearing from folks who were a part of that. Anything else that I might be missing?
