Hmm, interesting. I'm not totally against the idea. We should talk
about this at ADASS and the Interop. i think a JSON representation
could be useful, although I'm not so sold on taking the XML out of
the TCP transport layer.
PS. Matthew, you still ow me a page or two on the Jabber transport
layer for the VOEvent Transport paper for the HTU proceedings.
