I stand corrected. At first glance to the page I thought it was the Wavepoint II Access Device. Upon further inspection I see what you are talking about.

If you purchased the ethernet only version and a card you would be out just a little more than an Airport. Doesn't really say anywhere but I wonder if you could talk from card to card. I have a WaveLan card in one of my PC's along with a wired nic. If the card in the convertor would talk directly to the card in the PC without the access point present then it might work pretty well.
