Lowering the cost vs speed of internet service is hardly in the
same league with curing cancer.  Remember, anyone can now get dialup
for low cost or broadband for high cost (see www.agristar.com).
BPL at best is more bits for less bucks.  There is no demand
for more bits for more bucks.

I mentioned that in my letter.

Larry mentions that BPL will use WiFi for the last 100 feet
and fiber for everthing but the last mile.  It's only the
"last 5180 feet" where BPL uses power lines.

Attacking BPL on economic grounds isn't going to work either.
The proponents have their own money to throw down the rathole.

Powell's case for BPL is that we need more competition.  WiMAX is yet
another competitor, but Powell's philosophy is the more the merrier.
BPL and WiMAX are not mutually exclusive, anymore than FTTH, which
is mentioned in the article.
