I don't think you can/should do that. First of all you have to define what the
"other end" is and how you got there. It is perfectly reasonable to expect
the output of a URI to a POST operation to cause a car to be delivered
to my location within the next 10 minutes. Its called a taxi service.
I can even define one that will purchase and deliver a new car in less
than 24 hours. Given the latency of some email those time periods
are prefectly reasonable network response times.

If in the RDF/web services there is a URI (even an HTTP one which irks me
personally) that denotes the actual physical car, it is very reasonable to
have a series of simple processes that are the equivalent of a GET
on that physical thing. This is essentially what Amazon is in the
business of doing with its One Click service. Denying that those are part 
of the architecture is arbitrarily decided that the web architecture is 
limited to particular transport layers which isn't a good thing.

RDF is an important development here because it finally gives us the
ability to determine from a consuming application just what the semantics
are of that GET operation. Especially when you can get into statements
about what representation of the 'car' concept you want. Do you want 
a digital representation in JPEG or do you want it to appear out front
for a test drive?

You asked for it! ;-)
