SOAP-over-UDP support in CXF?

[Steve Cohen]

I know there is a SOAP-over-UDP spec but I don't see that anyone has 
implemented a package for handling it.

I am looking to modernize a legacy application that uses UDP packets (in 
both directions) as a data-transmission mechanism.  It's written in C 
with C structs passed in datagrams between the client and server.  The 
system is kept in synch by means of "synchronization" messages sent from 
server to client (that's the reason for bidirectionality).  These are 
used instead of "return values" to the original messages.  Messages sent 
from client to server do not expect returns.   Since the server part 
will only be wrapped (not a complete rewrite) it seems necessary to keep 
the UDP semantics in any modernization.

SOAP-over-UDP may be overkill, but can anyone tell me if it's been 
implemented, either by CXF or someone else?
