Changing a webcam to wireless

I want to change my webcam that you normally connect to a computer via a wire to a wireless webcam that would transmit to a computer with a wireless card. Is there any way to do this?? :? If there is then can you tell me how, in simple language if possible, i am a bit of an ameteur!

Have a look for a product called NSLU2 by Linksys.
£50 and it will do it!!! as long as yr wireless card and webcam is supported

I am at present using one as a torrent server,HTTP server, FTP server and SAMBA server
