21.com had a similar idea a while ago, but seem to have dropped off the map.

I forget who it was that had the idea of a "smart lightbulb" with a miner chip in it, but haven't seen that come to market.

I believe the whole "consumer device with a mining chip in it" concept is a non-starter, due to power usage (forget Green certification) and requirement for Internet access (lots of folks that don't have WiFi of any form or any interest in it) and the additional cost of such an item.
