PayPerPost Acquires Performancing

Michael Arrington is announcing on TechCrunch that PayPerPost is acquiring Performancing, the blog advertising platform.

A number of blogs in the online marketing sector use Performancing (such as Linda Buquet and Steve Rubel among 28,000 others), and I wonder how this will affect or not affect their use, of the Performancing platform.

Is this a complete buy-out or will PayPerPost only be acquiring part of Performancing’s services? Arrington says the Firefox plugin is not being acquired and will be spun-off, but that seems odd to me.
