Actually, I think Mike has pointed out the key here though: REST is an 
*architecture*. If you used RPC to *implement* REST, it would be just 
as well be called REST as REST using HTTP. I think that is a crucial 

The REST *architecture* has merits for some classes of problem, no 
doubt about it. I don't think anyone would claim that it is applicable 
to *all* classes of problem. REST over HTTP is equally usable for some 
subset of the problem domain to which REST is applicable, and equally, 
I don't think anyone would claim that it is applicable to *all* REST 

This really reminds me of the DOM days....  people can't see the 
architecture for the implementation, or the implementation for the 
problem domain.
