on Shibby's inbound QoS "This is NOT a Global Maximum" is printed. This is where its different than toastman.
Toastman uses a global max for inbound as well. See the screenshot of toastman below, you'll see the inbound QoS looks different than other implementations.
Davesnothere, if you're on Bell or Wholesale (Teksavvy) ADSL, there's yet another issue to deal with.
I've never been able to achieve success without setting my upload max to a rather low value (about 350kbit out of 640kbit). there's some congestion that occurs on mixed up/down traffic stress that I haven't been able to resolved (other than setting my upload max very low). I haven't had the chance to test this with Cable or vdsl
