P2P may be falling on hard times in at least one sense; BitTorrent confirmed a 20% layoff but said the move had nothing to do with the Comcast throttling issue.

Comcast has finally admitted to taking steps under its usage agreement to block or interfere with P2P traffic, at least that of BitTorrent.
