All of the alternative ways you describe to accomplish remote meter reading 
would require the power company to pay for 100% the equipment.  With BPL, they 
expect that the BPL customers will fund the majority of the equipment costs, 
with the utility use of BPL coming along for little or no money.  If the power 
companies use it for utility control, they may also get away with rolling some 
of the costs into their rate structure.  That is why they are interested in BPL 
and not interested in paying for cable or DSL to accomplish their control 

Don't discount that time-of-day meter reading. If it is successful in reducing 
peak loads, that alone could be worth a lot of money to the utility companies.
