There are already 2 chat packages available. Why creating another one?
1. Chat Module (in file storage)
(and an improved version I've been working on)
2. Jabber Package under CVS
openacs-4/contrib/packages/jabber
If you want to add that to CVS you have to send that to community members with more rights on the oacs box. Try to add it to the contrib folder in cvs or just upload it to the above file storage.
