I would love to make the source available. But there's no getting that genie back in the bottle once you go that route. I wanted to release it and get some feedback before deciding what to do with it. That said, a server that supports the examples on this page is pretty trivial to implement (especially if you skip the pubsub stuff). I had a working prototype in a weekend. Multiple implementations would probably be a good thing.

EDIT: also, the current state of the code base is not something I'd be excited about having my name attached to ;)
