Yeah, no, +WEP should work. I haven't specifically tested it but I see
no reason for it not to work.

Well, I was really thinking of RSN/WPA, and last I checked
wpa_supplicant didn't even support that with IBSS, and I think it
requires userspace MLME because you have to do the auth/assoc sequence
with each peer etc.
