Easy XMPP, small improvements can make a difference

The easy XMPP initiative tries to identify all the small UX glitches and fix them. That's a great first step in the right direction. For user discovery I would love to see mobile clients to check my address book, auto add contacts with a XMPP address and automatically check contacts email addresses for XMPP capabilities. This would be a easy, privacy respecting way to auto-populate the contact list.
