Would it be possible to publish a list of MAC addresses that were
operating in ad-hoc or AP mode? If all of the happened to come from a
signle manufacturer, that might be a very interesting data point.
A lot -- possibly even a majority -- of the cards I saw operating in
ad-hoc mode were using mac address prefixes that aren't assigned
to any manufacturer by the IEEE [1]. Many started with the octet "C0".
I even saw a card in ad-hoc mode with a MAC address of FF:FF:FF::FF:FF:FF.
