>This does not mean a Jabber ID is an email address. Though on many mail providers these days, it's the other way round that's true. A lot of people use GMail, but few realize that this means they also have a JID (Jabber ID) and can use XMPP, since Google opens their servers. It's a shame, really. Google seriously missed a chance to kill all of the mess of a thousand and one IM providers (each with their own, proprietary protocol) and replace it with the open and partially decentralized XMPP protocol, which anybody can implement and run.
