Thanks for the info.  I read through the SOAP-RP spec and it looks
promising.  I was wondering how you view it vis-a-vis BEEP?  SOAP-RP seems
to handle routing information plus low-level transport with its TCP and UDP
bindings while BEEP seems to be geared as a framework for building async
application protocols (not necessarily tied to web services).  Is this a
fair assesment?  Both protocols seems to provide a lot of the same
functionality but take different approaches.

You might want to take a look at SOAP-RP and DIME which you can find
linked from [1].

SOAP Routing Protocol (SOAP-RP) [2] is a simple SOAP-based protocol for
routing SOAP messages over a variety of protocols like TCP, UDP, HTTP
etc. It can be used for one-way messaging, two-way messaging like
request/response as well as peer-to-peer conversations, etc.

Direct Internet Message Encapsulation (DIME) [3] is a lightweight,
binary encapsulation format that can be used to wrap SOAP messages and
binary "attachments" into a single message construct.
