Doing full IEEE 802.11i/802.1X authentication for adhoc networks would
indeed require a lot of changes and not only in wpa_supplicant, but also
in the drivers. Basically, one would need to integrate authenticator
from hostapd with wpa_supplicant and allow wpa_supplicant to act as both
the authenticator and supplicant between multiple adhoc nodes.

There has been some work on this area, but I think quite a bit more will
still be needed to get this working.
