Wait, do you accept that you could "do" your other case in REST?

As you describe it, your problem sounds like an artificial intelligence
problem quite unrelated to issues of protocol. Insofar as REST
discipline is highly compatible with the Semantic Web technologies (and
was explicitly designed to support them), I would look for your solution
there. If you can clarify the semantic issues involved in having two
computers negotiate about "ski trips" then REST could easily handle the
protocol issues. i.e. if you come up with a DAML schema that makes all
of the questions and answers *possible* then I can show you how to
compose the questions and answers into dynamically assembled HTTP

I would guess that REST+SemWeb technologies probably stand a much better
chance of tackling the issues than other approaches (CORBA, Messaging
Software, EDI, etc.)

Come discuss XML and REST web services at:
