First I would like to say that I could not agree more with the
vast majority of your statements and your excellent analysis. "Me
too!" gets boring so I have not bothered to actively signal assent.
The only statement I don't agree with is the scenerio listed above.
Our experience does not match the scenerio you outline.
We sell high speed Internet access via both ADSL and DOCIS
modems. We have found that customers are quite willing to do
self-installs of their own splitters and that they do not seem to want
to move "room-to-room" in the manner you describe. Rather, they are
quite happy having in-house networks that are seperate from a phone
Right now, I am sending from a laptop on my kitchen table in
rural Maine. The laptop, like all of our five computers, has a
Lucent wireless ethernet card ($60). We have an wireless node
connected via Ethernet to an integrated Ethernet hub/router/modem
which acts as firewall. Since we are about 8 miles from the CO, we
use ISDN rather than DSL.
The last thing I want to do with my laptop is move around the
house connecting it to *any* wires. As it is now, I can move around
to any room at the drop on a whim. I also can't imagine wanting to
move the TVs around.
Talking to others, I know that the way I use the service is
common. I have never heard of anyone saying they use either IP over
DSL/DOCSIS in the scenerio you describe.
So while I agree with you that the scenerio you describe is
possible, I do not agree that it is the only one, the most common one
or even widely users. I do not believe that the design should be
constrained to meet this scenerio unless satisfying this contraint
causes no burden.
