I haven't followed this discussion closely, but a TCP level mechanism
would be difficult to use over HTTP because HTTP connections are
nearly always multi-hop and so use multiple TCP connections. So unless
intermediaries already have compatible congestion behaviour
implemented (which I doubt is the case, though I'm far from an
expert), you'd need to be able to signal them via HTTP extensions...
which comes with the obligatory disclaimer that the desired end to end
behaviour won't occur until the vast majority of existing
intermediaries are upgraded to support those extensions.

Mark.
