HFSC seems interesting, but does it really work well? I am not afraid of 
new stuff, but bleeding edge is probably too risky.

That HTB problem, I guess you mean it is possible to have available 
bandwidth, but when some of it has been distributed between users, all 
users' ceils go below their quantums?

But that implies that users have low ceils? Wouldn't it be solved by 
setting all users' ceil to the full link bandwidth?

The doubly linked list patch you mention, I believe it should be in 
vanilla kernel since 2.4.20-22 or something? I use 2.4.27 here. If not, 
do you have a link for it?
