The usual reason for decisions like that is to be transport independent. 
  My thought is that the HTTP variant should be optimized for HTTP, even 
if you happen to have other variants.

Just to be clear, I'm suggesting that there be a single URI for what you 
currently use both a URI and an instance ID for. One easy way to achieve 
that is:

Even in CORBA, each object has its own ObjectID. People tend to think of 
the URI as the "protocol" access point on the Web, but really the TCP/IP 
port is the access point. URIs should be analogous to ObjectIDs, not ports.
