Computer controlled wireless mains switch

[slampen]

Hi,

Can anyone recomment manufacturers or brands of computer controlled
wireless electrical switches?

I need to have a linux box some kind of transmitter which controls a
number of mains switches wirelessly.

Or it can be 8202.11g wireless network 'client' modules with switching
relays and delivered with proper driver software which makes them easy
to control from scripts.

Thanks for comments and tips on such devices.

regards Geir
