A Professor at the University of Michigan had done a nice business study report
on BPL. The URL turned up busted, so for those that may link to it, here is
the new URL:
http://tprc.org/papers/2003/246/Tongia-PLC.pdf
For those that haven't seen it, it is a good read that may be of some interest
to your local utility.
