Note that Google itself properly refers to the protocol as XMPP. You should too.

Jabber is an organization and a company associated with the early development of the protocol, but the standard itself is not owned, controlled, or trademarked by those guys.

Google only mentions "Jabber" as "this is how you tell Gaim etc to speak the XMPP protocol". Somebody ought to bugfix Gaim to fix the misterminology.
