level of encryption, but I'm curious about the level. If a power grid is

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.

Cable connections are shielded. If signals "leak out," the cable company
is required to fix it.
