Now it gets real: standards-based SOAP-not-only-over-HTTP with SOAP-over-UDP:

Many application protocol patterns match the semantics of the User Datagram Protocol (UDP) [RFC 768]. Some do not require the delivery guarantees of TCP while others make use of multicast transmission. In order to allow Web services to support these patterns, we need a way to map SOAP envelopes to user datagrams. This support is essential for services using WS-Discovery, where the use of multicast and need for low connection overhead makes UDP a natural choice. It is anticipated that other protocols will have similar requirements. This specification defines a binding of SOAP to user datagrams, including message patterns, addressing requirements, and security considerations.
