Kind of like multi-band cell phones. Alan's point is still very valid. From a poweruser point of view, if I specifically tell my wireless client "You must obey US laws", and then I wander over past a broken imported AP, I don't want my client to _expand_ its allowable range. IMHO, userspace should be able to forcibly restrict wireless frequencies to a certain regdomain (or leave unrestricted and passive-scan-only), and specify how AP/ configured regdomains act. Given the range of possibilities, I think that a userspace daemon monitoring events and dynamically configuring the useable frequencies would best. That way the userspace daemon could be configured to ignore APs, union/intersect the APs with the configured regdomain, ignore the configured regdomain in the presence of APs, etc. Cheers, Kyle Moffett -- I lost interest in "blade servers" when I found they didn't throw knives at people who weren't supposed to be in your machine room. -- Anthony de Boer
