yeah I am neutral again on this now following ignitions input, I will just stick to I wish that they be using QAM64

When they can, they will.

For those interested, part 2 of this series on Ars Technica is now up:

Meet DOCSIS, Part 2: the jump from 2.0 to 3.0

interesting that interleaving on cable only adds small latency unlike adsl where it can go crazy high.

Now if only they would turn interesting stuff like this into a TV series, presented by someone like Neil Morrissey or Kate Humble.

Cable lives in a system that is supposed to be closed, insulated and shielded. ADSL runs on unbalanced and unshielded twisted pair and in some cases requires extreme interleave to mitigate noise spikes.
