In the most proper context, this isn't really a crack.  What they're
actually doing is utilizing the parallel processors on the GPUs to brute
force the keyspace.  They haven't really found any vulnerability in the
protocol (as was the problem WEP), rather they're just able to check all
the keys.

What I haven't seen a clear indication of (although I haven't read all the
links above) is whether it affects the enterprise WPA stuff.

In any case, just use a VPN if you're really paranoid.
