Could you elaborate on the failure cases? We have found this to be
useful in practice to prevent applications from reading large amounts
of data off the network so it would be nice if it were supported.

It works fairly well for a small number of bulk streams when no packets
need to be dropped. The results get very inaccurate for higher number
of smaller streams when packets start getting dropped. The problem is
simply that currently none of the congestion notification mechanism
work in (internet) practice.

Therefore I think that it is not worth the effort. If you think
diffrently, I will be more than glad to review code. So far I haven't
seen anything that would work on ingress.
