I'd rather see "clicktrails" tracked by browsers sending Session-ID: 
lines (which we talked about here a while ago, Bill put in emacs-W3, and 
I'm hoping is on the list for HTTP/1.x) than by persistant connections.
You could also use that ID as a key to other stateful information the 
server wants to keep, but only for a short term.  Also, maintaining that 
connection might not necessarily improve bandwidth - the thought of busy 
servers with 1000 concurrent parallel connections all sending KEEPALIVE 
packets is a little scary :)
