Yeah I have all that down, and even some servers running it already.
The problem is you have to specify separate download and upload
speeds. I want to specify one speed for both direction - so its
shared.

If I have a 2Mb connection, I can upload at 2Mb, download at 2Mb, or
do both simultaneously at 1Mb. So defining 2Mb on each direction
won't work, because if I try to use both at once the most I'll get is
1Mb and I won't reach the queue limit of 2Mb (meaning the queue isn't
the bottleneck, meaning shaping won't work properly). If I define 1Mb
for each direction, I'll always be limited to 1Mb, regardless if the
other direction is in use; that would leave idle bandwidth.
