right - this is structurally nice basicalyl, leveraging off the proxy
service at the edges of the problem network...- but say you MOVE from
a place where this is a good mechanism, to being near (e.g. i am on a
plane browsing over a slow uplink, but fast downlink, then i land  and
go to an office, while looking at same web content, where i have a
3Mbps IR link from the laptop to a terrestrial wideband net....

how does the proxy change what is doing (e.g. get out of the way!)??

yes, but that's far too static....i'd like it to autoconfigure...

also, you need at least a syntax for specifying this even if its just
preferences (though if you dewsign it righ,tr it could be part of tha
autocoinfiguration client<-> proxy and proxy server gateway <-> real
server auto set up...)

so what should that syntax (and even protocol) look like?
