[TriLUG] DSL or RoadRunner?

That was exactly my point Reggie. (Read my comments again) The cable
providers can indeed use the architecture proposed in TR-059. The
question then is whether or not the cable providers will be open to it
or will they keep heading down the DOCSIS road for their QoS needs. I
think this will be driven mainly by the ASP and CSP (thats Content not
Cable) offerings of the near future, and if these offerings don't
materialize then nothing much will come of either DOCSIS 1.1+ or TR-059
in the cable space. Secondary dial-tone alone is not strong enough to
carry the day, but it may have already encouraged service providers to
deploy an RoI burden which deters them from investing in the
infrastructure defined in TR-059.
So, for the Home Linux User my inclination right now is to suggest
getting DSL if they have a desire to take advantage of QoS / BoD as soon
as its available in their market.
FYI I used to be a BellSouth FastAccess user. Today I am a RR user.
For a while I did both.
