Nice. Thanks for sharing the writeup and demo. You'll probably want to rate and character limit it.

edit: also perhaps deny a single user from duplicating tabs and saturating the bandwidth. ...but it's a neat demo and useful for trusted users.

Thanks, yep i need to add that. I just put it together from the fork of chrismccord chat example, did'nt put much thought into the rate & limit.

There should be a spam-filter based on number of post per users compared to other users in a given timeframe. The chat is now flooded by a user posting links to porn-pages.
