User = IP address (i.e., just to keep it simple).

It doesn't have to be perfectly fair, it just prevents one user from crowding everyone else out due to non-reacting flows. >> Note also, that we have so many easy problems to tackle, if this one >> turns out to be difficult I'd be loathe to make it in scope. It's not difficult; it just needs to be spec'd, and the spec doesn't need to be precise. The goal is to do something that is per address at least, and prevents crowding out, and that's already supportable in at least one existing OS.
