Brubeck has experimental WebSockets support coming up soon. The basic idea is that all of the socket proxying takes place in Mongrel2 and Brubeck handlers simply process messages from the socket. Brubeck, in this design, is asynchronous and full duplex, just like websockets themselves. The other models I've seen seem to require hooking your webframework up directly to the servers, without any socket proxying support. That might be useful for small installations, but it is a core design goal of Brubeck to make life easy as you scale up. Having Mongrel2 proxy the connections is part of how we do that.
