If I'm paying the same as the bidding cost for advertisers, then I'm all in, this is super sweet. If I'm paying some vague hand-wavy fee that reduces my ads, but doesn't correspond 1-1 to what advertisers are paying then forget it.

Edit: Apparently it is a 1:1 mapping and unused money rolls over until next month. I was wrong. Thanks cmpb for pointing that out.
The way I would be in 100% support of this would be if I could go and "top up" my ad-support-budget. Say I add $50.. and from then on every Google served ad gets swallowed up and my balance gets deducted whatever the bid price was, with the same % going to the contributor site.
When my $50 is up, ads return. I can choose to refill as I want, or set it up to auto-refill with $20 when it runs out, sending me an email or whatnot.
I really really really like this concept, but man, they need to be really honest with their implementation.
