I don't know that anyone is looking at 802.11 (not 802.11b) solutions, but just a heads up so that no one wastes there time. The Sohoware CableFREE products to not work with other 802.11 devices. From Support@sohoware.com:
Unfortunately, our CableFREE products are proprietary and will not work with
other wireless devices.
Also, due to this, I suspect these products won't be around very long. Maybe in a few months we can get a bunch for pennies, but I won't go spending good money on them hoping you can grow your network (or even replace dead units).
