Hmmm.. the assertion that "All Web services have identity, and are 
therefore resources" doesn't seem right to this lurking observer.  I view 
"Web Services" as one way of getting to a resource, not as the resource 

A Resource has an identity and a collection of mechanisms a resource 
consumer can use to get at that resource.  Web services are just one of 
those mechanisms.

I believe my disconnect here is purely a matter of semantics so perhaps 
you could ellaborate a bit more.  What am I missing?

Doesn't this count?

"A resource is defined by [RFC2396] to be anything that has identity."
-- http://www.w3.org/TR/webarch/#identification

Or did you want something more specific than a punt to 2396?
Personally, I'm quite happy with the punt.

I'd suggest that;

"All Web services have identity, and are therefore resources."

is as far as we can go with that, at least until the definition of what
a Web service is, is figured out.  The current one is still very fuzzy,
