The problem with udp is basically that you don't have the statefulness of tcp that means no complicated handshake that involves cryptography can be used, and the term automatic includes not asking the user. I think it is highly problematic to automatically create a session to a potentially malicious device without even telling the user and, what you too proposed, syncing (although my system would work totally without syncing as it works directly on the phone without a local copy to keep in sync), which would even involve sending data across the wire.
