i always thought the main difference between ADSL and cable contention was to do with where it starts. with ADSL you essentially have a dedicated 512 ( or whatever ) line to the exchange in the form of your phone line ( i dont think this is strictly true, but its near as dammit ) and then once you get to teh exchange your connection shares the pipe from teh exchange to the internet backbone with anyone else on the exchange.
with cable you are sharing the local loop bandwidth with other people in your area ( by local loop i mean the cable outside your house ) so you are 'contending' with your next door neighbours...but that bandwidth is then not contended at the head end....
