If you find no good solution at the Apache level, you can 
try at the OS level.  Linux has some IP traffic shaping tools
that you can compile into the 2.2 & 2.4 kernels, called QoS
in the make xconfig.  Check out:

Also, on linux, you'll want the latest cbq script which makes
dealing with the tc config much easier.

And though I have never used it, dummynet for FreeBSD supposedly
has this functionality has well:

If you like shelling out the big $$$, Packeteer puts this in a 
box for you:  http://www.packeteer.com/
