I'm curious to know why you don't think a CPC model on a large scale could happen.

  My reasons relate specifically to email marketing. Off the top of my head: 1) It's difficult, if not impossible, to combat click-fraud. There is no javascript running on the client-side to help, and there is no verification that the ad that was displayed wasn't something like "click me to unsubscribe" 2) Ad content in email is scrutinized more heavily and blacklisted more liberally than any web-based content. It would seem that one mistake would sink the entire ad network and any newsletter that uses the network.
