Thought about using these two as well, latter I would've 
certainly used at some point, former I wasn't so sure 
of, because websockets need some weird webserver 
configuration (at least for nginx), and ratchet's flash-
fallback uses an own port, which has to be opened in my 
firewall …

Neat!

We should definetely work on this together, instead of 
making two chat-apps :)

Are you in IRC?
