Reliable Messaging Summary - Cont

Let me try to add to the summmary I posted earlier of the Reliable
Messaging threads to cover the more recent activity.  Again, I may get
this wrong, but if I do please help out.

It seems to me that in the recent, sometimes very detailed, threads we
are now seeing a second model for Reliable Messaging.  That is, the
first more or less takes the ebXML spec as the starting point, the
second pretty much builds on the concepts embodied by TCP/IP.  These
approaches appear to have many features in common, but I do not think
that they are identical.  I am, unfortunately, unable to select a
representative set of references on the TCP/IP-like thread, other than
the already referenced "six level" starting point.  Perhaps the experts
would care to summarize where it stands?

It seems to me that it would make sense, in a potential handoff to XMLP,
to make them aware of both approaches and let them reconcile them or
whatever.
