Thanks. We already announced bfq there, and it received a warm welcome. 
But there is a tough hurdle to overcome: the maintainer prefers that 
there is only one scheduler, i.e., cfq :)
I am currently discussing these issues with one of the guys involved in 
cfq development.
In the meanwhile I just wanted to let other people know about bfq and 
the benefits it provides.
