True, it's WPA2 in IBSS mode and it is standard (you can find its description in
the 802.11).

Right now, using OpenWRT and one of the ibss/rsn enabled drivers (like ath9k,
ath5k, iwlwifi and others..), it should work out of the box[tm].

As RSN, it establishes a PTK for each pair of nodes in the Ad-Hoc cell and a GTK
for the broadcast communications.

The only drawback at the moment is that broadcast packets are encrypted in sw
(so reducing broadcast throughput a bit), but I don't think this is a real
problem.

Cheers,
