@ifixcoinops I'd love to hear your thoughts on the idea of setting up some sort of (FOSS/non-commercial, obviously) hosted thing for doing stuff like this, so that people can run banner exchanges like this on their site and accept submissions without needing to install/maintain some piece of software for it themselves.

Seems to me like it could help encourage other folks to do the same thing by lowering the barrier of entry, but you've probably spent way more time thinking about this than I have :)
