When I looked in to this it seemed that the current state of affairs is that
WPA can only be broken by brute-forcing the key. I don't recall if that
could be done 'off-line' or not. My memory is that the needed info to
attempt bruteforcing could be done by simply receiving....no need to attempt
to associate to the AP was needed. I'm not really interested in
disseminating links to tools that can be used to break wireless security, but
simple google searches will give you the info you need.....and the tools are
in the ports tree for the most part.

Fortunately WPA allows keys that put even resource-rich attackers in to the
decade range to bruteforce.

That would not appear to be a limitation of aircrack-ng
http://www.freshports.org/net-mgmt/aircrack-ng/

aircrack is an 802.11 WEP and WPA-PSK keys cracking program that can
recover this keys once enough encrypted packets have been captured.
It implements the standard FMS attack along with some optimizations
like KoreK attacks, thus making the attack much faster compared to
other WEP cracking tools. In fact aircrack is a set of tools for
auditing wireless networks.

That said, I haven't (yet) tried it myself ;)
