I have always suspected that this would happen. It appears that even a legislated elimination of P2P will not stop file trading now that Pandora's Box has been opened. According to ITworld,

A Pew survey of 1,421 U.S. adult Internet users found that informal file-sharing networks are used by 19 percent of music and video downloaders, with MP3 players, e-mail and IM (instant message) products popular mediums for transferring files between friends and family. The results of the survey suggest that legal action by the Recording Industry Association of America (RIAA) and others is shifting file swapping to other online avenues, even as file-sharing activity recovers from recent declines, Pew said.

Of course, DRM might eventually put an end to most of these methods of sharing files.
