Ah, looks like BitTorrent, which maintains the peer-to-peer file sharing system, may indeed be raising a big new investment round, a rumor we mongered a couple of weeks ago. Om Malik's heard Accel Partners may be coming in as lead in a new injection of up to $25m. Accel is also an investor in Facebook, the social network for college students. Valleywag had picked up, separately, that the round's heavily over-subscribed.
