Exactly, but what if you want it to behave it like a cohesive contact. This is 
not possible at the current stage. So non-symmetric Ip2 functors would make 
sense here, right? And looking at the variety of material we have (some are 
not inherited from FrictMat) I can see some more benefits.

Ok, I will try.

Any idea about the goReverse? Can it be removed?
