Ok, thank you. I forgot to mention I reviewed your previous message and 
also the code and found no bug. :)

This question was not concerned with overhead but more with "what do I 
need to do in my contact laws now?".

I'm still wondering how dry friction + capillary law will interact now, 
since ElasticContactLaw will delete interactions that the capillary law 
still needs (they are two different engines working consecutively on 
each interaction, one is not distant, the other is).

It looks like it works in current svn though.
