I'll be committing the CAIA Delay-Gradient (CDG) TCP congestion control 
algorithm shortly. It's still experimental, but it has some useful 
characteristics in terms of keeping buffer utilisation minimal whilst 
achieving acceptable goodput even in the face of competition from 
loss-based algorithms like NewReno. I've included a few relevant links 
at the end for anyone who wants to know more.

On the larger topic of de-bufferbloating the kernel, I'm not aware of 
anyone who is systematically identifying buffer points and "fixing" them 
if they are found to suffer from bloat problems.

Cheers,
Lawrence
