It's mostly no where, as far as I know. It never really got off the ground. Which is great if you A) live somewhere with a lot of 2.4ghz interference (cordless phones, microwaves, other wireless networks) and B) have a laptop with a dual band card. When I was running it, I ran a 802.11b AP at the same time for other people, but it was real nice to have my laptop have its own slice of spectrum.
