Sorry, they can't see your hard disk via the power lines. There are few places with broadband over powerline at this point. If you don't have a BPL modem and ISP service over that modem, you don't need a "firewall" for your powerline. The guys in dirty night shirts are afraid of technology that hardly exists...yet.

You will know when BPL comes to your neighborhood. It will be apparent when your broadcast band AM radio becomes a worthless pile of squeals, clicks and digital hash.

Thanks again Myrddin, I should have included a /saracasm with my earier post about a firewall, sorry about that.
