Any good web chats?

Question

Are there any good team websites, preferably in Python, ideally with CherryPy or Trac?

This is similar to https://stackoverflow.com/questions/46612/whats-a-good-freeware-collaborative-ie-multiuser-instant-messenger#46660 , but a few main differences:

1) I really want to host the server.

2) I don't care if emoticons are enabled in the client.

3) I would like two options for users:
 a) The ability to host a private IRC, such as a chat, on my Trac page (or a link to such a page),
 b) allow remote clients to also interact.
