yup, that indeed does work. I have an FP iMac. All you need to do is to install a Aiport Card inside. Turn on Internet Sharing in System preference. I plugged a SMC 802.11b PCMCIA card into my DELL laptop. ( of course being a windoze machine you gotta install the drivers first...etc...) but that all folks. The drawback is that you cannot use encryption. At least I was not able to get it to work using it. I set the channel to auto detect ( in the DELL) Each card maker has their own program for the wireless card. So to answer your question, YES it does work!! email me if you got any problems.....
