I can tell you right now that WPA2 CCMP PSK can be broken - I have a .cap file right here from my own network that is set at exactly that.
Now I venture into hazy memory rather than hard fact, but if you do Peer-to-Peer networking with wireless, the assosciation and joining algorithyms are different (or modified at least a little) to the normal router+client setup.
Someone should confirm that, but I usually treat point-to-points as "secure enough", to pass in most of my pentests - it's purely a weakness in my wireless knowledge though, I can't really confirm it either way.
Still not underestimating the power...
There is no such thing as bad information - There is truth in the data, so you sift it all, even the crap stuff.
