Broadband Over Power Lines is a concept that has been floating around for years. But problems with interference and other technical limitations have made it seem like vaporware. Apparantly recent advances  have  given BPL proponents a boost. Two power companies in California are now going to begin testing the technology. Unfortunately PG&E is not one of them.

This article from Cnet spells out the details. If it works, BPL could provide more competition for broadband services which should drive down prices. Additionally, BPL could be a viable alternative in rural areas that are not likely to see DSL or cable reach them any time soon.
