IBSS + WEP works at least for ipw2200 and other non-mac80211 cards; I can check it out with mac80211 if you like. One thing though, if mac80211 isn't going to support IBSS + WEP for a while, we should find some way to push capability bits to userspace that say that. Otherwise there's no way for NM to tell that the driver doesn't support it, and thus to not even show the options in the UI. Any particular reason IBSS would require a userspace MLME? There shouldn't be any rekeying of any kind with adhoc, since there's no central station to coordinate the rekying. AFAIK with IBSS you just use the given PSK at creation time, and never change it. That shouldn't be too hard to handle, right?
