How much privacy are the BPL folk promising? I have to figure there's some
level of encryption, but I'm curious about the level. If a power grid is
used for a network, than the common signals will be available at any power
outlet in a whole area, even for non-subscribers. Looks like a high tech
party line to me.

Note that this is not a unique attribute, it is about the same situation
as that which exists for broadband Internet service via cable modems. I
assume that BPL would use the same protection techniques (mostly
depending on control of the receiving equipment, I think). This seems
to mostly work, I very seldom hear complaints about the security of
people's cable connections.
