Wireless Wake On Lan

I guess I’m probably not the only one to ponder the idea of using Wake-On-Lan (WOL) to wake networked computers. I’ve used it a few times.

I’m now considering a wireless network and because of the remoteness of the computer involved (and it’s proximity to my father) I’d like to be able to turn it on remotely. I’ve done a fair bit of looking around but haven’t had much success in finding a PCI Wireless Netowrk Adaptor with a WOL feature, has anybody heard of such a device? or is it just pie in the sky?
