Well, the question whether you are in danger because you seem to downlaod and/or share copyright protected files can only be answered with "Yes!". Every time you break the law you will be in danger of being prosecuted and punished.
Whether this danger is eminent, well, is hard to say. At the moment the RIAA and MPAA are pushing pretty hard to scare the people off of the P2P file sharing (buying out Bearshare and sueing LW).
I do believe that the hound dogs of the RIAA are always around, no matter of which P2P client being concerned. There will never be any absolute protection (except not downloading and sharing protected files).
