Electric outlet idea

It seems these days that everything is turning into something chargable via USB cables and a computer. I had this idea and wanted some thoughts on it good and bad.

What if electrical outlets had USB ports built in, allowing you to charge not from a standard outlet, but a USB cable straight into the outlet.

Great for offices, home, and international travellers that want a universal charging system. After all, it is a universal serial bus.

thoughts?

Definitely interesting. Especially once/if Power Line Communication becomes ubiquitous.

One parallel product :Traveller USB Travel Plug is available in the market ,which can charge your ipod, MP3, mobile, laptop… through USB.
