Or one could just create a separate device running a highly secure OS with a simple bitcoin client, and with wireless enabled so that it could connect to the internet. With such a secured device viruses and other types of attacks on the wallet would be highly unlikely, as there would be no third party applications, and installation of additional software would be disabled.
Then the safety of the wallet would simply require one to be able to physically secure the actual device.

Create a bitcoin space heater with 1 or 2 gpus and use powerline networking ?
In winter you could have a nice foot warmer as well .
This would be so amazing. If you could a thermostat working roughly accurately a little heater/fan that paid back the electricity that it used in bitcoin would be the best thing ever (for cold feet and for bitcoin).
