New Scanner For Pirated Multimedia

A new software scanner is available to copyright holders that can detect audio and video signatures, and consequently detect infringing web content.  It's called ACID, and the details are here.  Would a product such as this work in favor of Google in the Viacom/YouTube litigation?  Viacom is complaining that the burden should be on YouTube to police copyrighted material even though the statutory scheme nominally places the burden on the copyright holder.  Would a tool such as this make it easier for the holder to identify clips?  Would that undermine Viacom's arguments?  Stay tuned.
