I wonder how this is done in Google Docs? The approach may be a bit of overkill for a chat client though. Multiple users can edit a word processing document or spreadsheet simultaneously.

I've seen talks about how this is done conceptually.  It involved the command pattern and there was a way to ship (serialized) objects from server to client.  I think it used the Google Chat protocol.

Docs being done in Closure, it's probably using BrowserChannel. If you run on AppEngine, you can use the Channel API. Otherwise, use WebSockets or anything Comet-like (long-polling).
