We've had good luck here with the Packeteer packetshaper 6500.

http://www.packeteer.com/products/packetshaper/index.cfm

We use it mainly to control [not block] music download traffic.

Anybody tried nmap against a Packet Shaper recently? I tried it against a box here which is no longer in service (not the 6500 model), and the result isn't exactly reassuring.
