Good points, Ed - I offer at least a partial riposte...

I suspect that the majority of the utilities that think they can handle
high-speed data already have the low speed metering system. A utility that
hasn't done remote meter reading has zero business jumping into the

They wouldn't, of course. But if the low-speed remote metering system can't
make them a decent return on investment, I doubt very much that BPL, with
all it's infrastructure and downstream costs would make them money.

Implementing an IP-based system on your own costs a whole lot more than
using the telephone system for dial-up.
Agreed that remote metering systems don't migrate to broadband delivery.
However, my original point was that, since remote metering has been out
there for ten years, if the utility isn't doing it now, they either don't
have the customer base to make it, and by extension, BPL, pay. None of the
remote metering stuff is obsolete or hard to get - it's a mature system.

BPL is untried on any significant scale and has large downstream costs
associated with it. I just don't see medium and small-scale rural utilities
making the leap. Suburban and urban utilities can't possibly make enough
inroad over DSL and cable. For who does BPL make sense, exactly?

I think the old V.24 systems are just too prevalent and inexpensive for the
IP-based system to displace them. They keep the system costs low. Migration
to IP just doesn't have enough payback to make it worthwhile, unless you
have a very high volume operation, such as a big department store.
Anyway - good discussion. I hope utility CFOs are having the same...
