RE: FW: ISPs slowing P2P traffic...

I'm not aware of MSOs configuring their upstreams to attain rates for 9 and
27 Mbps for version 1 and 2, respectively.  The numbers you quote are the
theoretical max, not the deployed values.

Well, according to wikipedia DOCSIS 3.0 gives 108 megabit/s upstream as
opposed to 27 and 9 megabit/s for v2 and v1 respectively. That's not what
I would call revolution as I still guess hundreds if not thousands of
subscribers share those 108 megabit/s, right? Yes, fourfold increase but
... that's still only factor 4.

Upstream capacity will still be scarce on shared media as far as I can
see.
