My completely uninformed guess is that they ignore it. I will hazard a guess that most scenarios involving "laptop as AP" are for support of devices that don't (or at least didn't) do a lot of sleeping, like other laptops. I'm still a bit "on the fence" regarding this requirement for AP mode. I think there is a reasonable body of users that would prefer a not-quite-right AP mode over no AP mode at all. John -- John W.
