Hmm well i think you can have protected identities in IRC, you have to password the user name. Im not sure how to do that. There are Java applets that allow you to embed IRC right in a web site.

Im sure you can put a simple chat box on the front page of the wiki. I have seen them on websites before but for the life of me i can't remember which ones right now.
