What we need is a mechanism for tuning on some "large window
extension" on the fly.  The host **is** the right place to determine
whether we need a "large window extension", as it probes for the
"right" congestion window size anyway.  Gateways **may** know
whether the extensions will be needed in some cases, but I don't
think we can count on such a mechanism in general.
