I think there are even dhcp options that could be used for that.
It should be quite reasonable to either set the proxy to the supplied
address (what about the port, then?) or (though this would be pain,
probably) ask a www server on port 80 for a proxy.pac if this option
is set in local dhcp server. I wonder what it originally way thought
for - should clients really only contact to one,2,..5.. specified http
server? Does this RFC come from Cuba? :-)

8.17. Default World Wide Web (WWW) Server Option
   The WWW server option specifies a list of WWW available to the
   client.  Servers SHOULD be listed in order of preference.
   The code for the WWW server option is 72.  The minimum length for
   this option is 4 octets, and the length MUST always be a multiple of
   4.
