These things have been "on again off again" for a while. IIRC, they were pulled a while back for FCC reasons. Something about being able to hook it up to an AP other than the WAP11, which could result in a device outputting more power than allowing via FCC part15.
So linksys did something with the cabling? or something and they were selling them again, but I heard they stopped again.
I have a WAP11 and was gonna get one, but every time I look has been one of the "off again" times.
