Hi Ricky and Steve,

  Yes.  In generally speaking, there're two models in the multipoint
comm., which are defined in the JMS as the 'peer-to-peer' model (P2P)
and the 'publisher-subscriber' model (Pub/Sub).

  However, I think that UDP is still risky. :)
  In addition, the current architecture of SOAP (rather than the AXIS)
doesn't make provision for the multipoint communication via SOAP.
It might be had a discussion ... in the near future.

Best Regards,

We certainly can use a Gnutella approach to multi-cast an event.

Rgds, Ricky
