Interesting to see this conversation explode in the Adsense forum, not the adwords forum. It's the Adwords side of the model that will make or break the system and clearly CPA is less prone to fraud than CPC.

With Google making Urchin free to adwords advertisers, the riting (for me) was on the wall right then. Google will not bin the CPC model - they won't have to. They will simply BLEND CPC in Adwords with CPA in adwords, with a twist... the twist is that you give Google money upfront as an advertiser and Google takes the balance out on a cpa basis as the adwords tracking converts.

No tracking? Google keeps your money
No conversions? Google ranks your ads lower accordingly

The model has been rattling in my head ever since last year's vegas. It is inevitable that this would be tried. Anyone know how I get on the Adwords side of this trial? (presumably there will be one...)
