I mean, you'd just want a separate subdomain or some such, and probably would be best to run it on an individual database. I've seen a few out there, but I haven't researched any, sorry... Rahenna would likely be tons more familiar with something like that, coding-wise, than I would. I just know that the possibility of one exists. And like I said, anything that'll be more reliable than silly fotobukkit is a step above. xP
