E-gads, man, there's a startup idea straight from heck -- using power lines to transmit advertisements to all the electrical appliances in your home.

Use the toaster and have it sing an advertisement for pop-tarts. The refrigerator would remind you that Jenny Craig was having a sale this week. You electric toothbrush would remind you that your local dentist is having a sale on tooth-whitening, as well as reminding you to floss. Turn the light on in the bedroom and have the lightswitch tell you about Viagra. And you don't even want to know what the bidet is trying to sell.

I think I just lost all desire for smart appliances.
