No I actually agree with you on that. Just saying that
anything that relies on per IP caching is bad too.

As I understand the idea was that the application knows
what flows belong to a single peer and wants to have
a single cwnd for all of those. Perhaps there would
be a way to generalize that to tell it to the kernel.

e.g. have a "peer id" that is known by applications
and the kernel could manage cwnds shared between connections
associated with the same peer id?

Just an idea, I admit I haven't thought very deeply
about this. Feel free to poke holes into it.
