   2. DHCP is a one time configuration retreival, the proxy config can 
      change dynamically, and DNS allows a mechanism to do that.
	   ( ie it has a lifetime )
      ( yes, DHCP has a lease, but I beleive that is meant to be more
	long lived )

That was not how I interpreted it.

I think most of the DNS servers I work with have a 1 week lifetime.

My PC has an IP address that will last for the duration of this ppp
session--ie an hour or two.

   3. Service location is an appropriate way to advertise a service,
      which I beleive the proxy is.  The browser is discovering
      an available proxy service, not a host configuration option.

What's the difference between discovering DNS servers and discovering
HTTP proxies?

   4. DNS is much more commonly deployed where the web clients are
	   (its usually a necessity ), while DHCP seems to be mainly
	   popular on PCs

I understand that point.

But I don't think that the implementation you propose is not as clean.

   Yes, if thats all your saying, but these days, a common config would
   be something like:
   set http:// to go to proxy1 on port 80
   set ftp:// to go to proxy2 on port 80
   set https://*.evil.com to proxy 3 in port 443
   set no-proxy for mydomain.com yourdomain.com thishost.thatdomain.com

   and more complex ones are coming ie:
   send HTTP GETS to proxy2 on port 80
   send HTTP PUTS to proxy3 port 80.

OK, but I don't see any settings where I would want to have such a
complex setup.

Like I might run a proxy server on one of my computers at home if I
get organized.  But I would only need one proxy.

I'd guess you need thousands of users on your network before you'd
need multiple proxies.

And with proxy cache hierarcies, I would htink it would always work
to ask your local proxy for the document, and let the proxy figure
out how to talk to another proxy.  I don't see where the client would
have to know about that.
