You mean with just the right amount of money, one could even win the most hopeless cases?

I don't think the judgement will based on the software or protocols per se because that would be completely hopeless. The question is probably whether they encourage or support copyright infringement e.g., directly or indirectly by their advertising. Thus even if the sentence is going to be "guilty" this doesn't mean at all that any other P2P software vendor will be considered guilty too.
