But the protocol is the application.  The methods in an application
protocol are the same kind (same layer) as the methods seen in an API.

The cleanest separation you could offer - and I've had this discussion
with Noah before - is to define the semantics of an application protocol
independantly of the specification of that protocol.  So we might
extract all of the application semantics out of RFC 2616, place them in
some new spec, and then be able to build new HTTP-like protocols with
that spec (say, that are optimized for certain environments - not that
I'm suggesting this is a good idea).

But that would still require the developer to choose the method.
Perhaps my last response to Stuart will help explain that better.
