Sure man! Excited to be a part of such an active framework

This is great! Mind if I hack on it a little bit too? I'd like to add a
splash page that asks a user for a user name and then uses a cookie value
for submission with each chat message.
I'd also like to put it in the demos, but perhaps we can coauthor a full
chat system and give it's own repo too? Would you be into that?
