Witness for the Prosecution?

The class action lawsuits filed against Commission Junction, BeFree and ValueClick. has everyone very intrigued as to how it will play out. But for me right now, the results is really secondary to what comes before. As we know different people have different ideas on what "Adware" is and what "value add" is and what ""cannibalizing" of the merchants sales is. So I wonder who Nassiri & Jung LLP will call as their expert witness?

I've heard a number of rumors going around that the most obvious candidates for the role have been rejected, declined it, or said they would not accept the role of expert witness. I hope I'm wrong, because outside of a very select group, there are not many people that I would say know the full extent of what needs to be searched for, found and presented.
