UDP support is being added in AIR 2.0. I don't know if that list extends to the Flash Player as well...

As far as I can tell the binary socket doesn't support UDP. Somewhere in the internals it must be presuming TCP or HTTP - or maybe RTMP. Anyway, it looks like my suspicions were right. I'll ask another question about what protocol Flex developers are using to communicate between clients for multi-player games.
