No need to keep wireless extensions on life support. >From my point of view WE is not on life support (yet) but instead very widely used. As an example, I still haven't seen any cfg80211/nl80211 user space tools in debian unstable. (Please correct me if I'm wrong.) There has been a lot of talk about cfg80211/nl80211 but unfortunately the migration progress has been very slow. I definitely want to see this background scan support in Wireless Extensions as well, otherwise it might prevent the real use of the feature. -- Kalle Valo
