I also have reservations on the cpm idea. At the moment, for delivering a quality click to advertisers I'm getting between 10 and 20 * the $2 cpm figure quoted. I'm not happy about the idea of delivering quality clicks for bargain basement prices.

My understanding as a publisher is that the CPM adverts will only appear if they are priced in excess of what you've earning via the existing CPC listings. So if you're earning $20-$30 CPM on your CPC (well done!) then advertisers would need to bid in excess of that figure for their adverts to appear on your site.
