You forget about the shared part of the Docsis. We all (on the same node) have to share the bandwidth on the channel(38 down and 10 up for Docsis 1.1, most markets). You start splitting up 10 (up) with a bunch of guys running 16/2 and the brakes go on in a hurry.
That really is not a DOSIS problem though, thats just a problem in deployment. They should not even be oversubscribing nodes in the first place. Nothing saying they won't use 3.0 and oversubscribe it anyways even if they have more bandwidth at headend.
