It depends on the client. TextSecure is an open-source XMPP/Jabber client for Android which does end-to-end encryption (OTR?), and adds contacts based on your address book automatically.
It also supports adding a new contact by phone number, and replaces the stock text messaging application, automatically upgrading text messages to OTR XMPP sessions if the other party is on the same network.
It doesn't do federation though, as far as I know.
