	Well, am I not correct in thinking though, that getting another
device to sniff packets (get a wifi card to monitor in promiscuous mode) is
counter with the end goal of securing and authenticating a client
successfully? I guess that the new device will not be able to see *all* the
packets as the AP sees them, and more specifically not see their content
unencrypted. Unless you  suggest to remove security as much possible for the
sake of debugging, but in the end that is what I want to debug... am I
missing something obvious in your suggestion?

	Regards,
