We use a Packeteer PacketShaper.  It definitely doesn't handle the
encrypted P2P file transfers that well, which led to our having to create
dynamic subpartitions for our dorm/wireless/VPN IP ranges to limit
unclassifiable traffic to 512Kbps per host based on IP address.  But
overall it seems to be working quite well with that arrangement.
