I don't know about the spec, but there is an issue wrt proxies if
clients talk to proxies via HTTP.  Most of my posting was arguing how
proxies and servers should be viewed as being pretty much
indistinguishable, although they are clearly used for mostly different
purposes today.  So unless we want to define a different protocol
for proxies, I would suggest we think about how they relate.

That's what I said too.

And there are two kinds of people, those who divide things into two
groups and those who don't. :)  I can imagine other subdivisions, but
that's a subject even further outside of the http-wg camp.
