All of these are great observations. So what's the cable HFC Achilles heel?

Correcting a previous url error on my part.

Sorry 'bout that, folks.

Agree, this is a great discussion, akin to a recent Cook Report accounting
of
best
effort considerations. Several startups (now going into year two) have
addressed
the cable-HF/C constraints you've mentioned. You may be interested in
perusing
these two:
http://www.narad.com
Another, Rainmaker Technologies...
http://www.rainmakertechnologies.com
appears to have fallen on hard times while seeking later round
funding. Not
sure of their disposition at this time, but doing googles on their name
reveal
some good articles on their approach to using wavelets to improve bit gain
over
black coax/fiber systems to homes and businesses.
Metcalfe has financial backing hooks and input into Narad, and Mark E.
Laubach of
COM21 fame (ATM over HF/C) heads up (headed up?) Rainmaker's technical
pursuits.
[[As an aside, I'm finding increased interest in corporate parks
(especially
those
that are boondocks-bound) where MSO fiber-based offerings are being
seriously
considered for WAN access, both of the type discussed above and enterprise-
tailored rings coming off local head-ends.]]

Folks,
This is a great discussion. I'm interested in understanding these types
of
limitations in the context of HFC cable networks. In my opinion, HDTV
channel bandwidth (30mhz?) , increased demand for voip, and growing demand
for IP connectivity is going to stress the cable network model as well,
forcing cable operators to convert everything to IP before going out
across
the wire. Any input is appreciated.
Regards,
Christopher
