??? I'll try to answer the initial question, which occurs at network layers lower than IP.
ADSL is usually supplied ethernet 10Base-T with ATM. Traffic shaping can be applied at the ATM(WAN/Copper) part of the modem, but this is up to the service provider.
Sure, you can shape your ethernet (LAN) component using a box (AppVantage Packeteer etc.etc.) but the functionality is already there on most ADSL boxes.
