You are still speaking ATM (and the above may still be valid), but: 
Could you for example look at the netdevice->type and from that figure
out the link layer overhead and compensate for it.
Obviously a lot more useful if such activity is doable in user space
without any knowledge of the kernel? and therefore zero change to the
kernel and everything then becomes forward and backward compatible.

It would be nice to have support for HFSC as well, which unfortunately
needs to be done in the kernel since it doesn't use rate tables.
What about qdiscs like SFQ (which uses the packet size in quantum
calculations)? I guess it would make sense to use the wire-length
there as well.

Didnt even think of that ;-> 
Is it getting too complicated? 

BTW, I forgot to mention one thing on the bandwidth issue is we could do
is send netlink events on link speed changes too; some listener
somewhere would then do the adjustment.
