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

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:

Another, Rainmaker Technologies...

 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
