The current development branch (0.7.x) has experimental code for RSN
IBSS (i.e., more proper use of 4-way handshake and key setup as was
specified in IEEE 802.11i-2004). However, I don't think there is any
driver available that would work properly with this now. mac80211-based
drivers may get quite close to working, but they do not yet support
multiple per-device group keys which is needed for RSN IBSS. This may
eventually provide the functionality you are looking for, but at the
moment, you are much more likely to get working results by making one of
your device an AP instead of using IBSS.
