Google PPA MAQ

Google has released a post on their Adwords Blog about the pay per action beta test, I called it a MAQ, as they said these were the most asked questions, I guess later it will be promoted to a FAQ.

Do pay-per-action ads show on Google.com or on sites in the search network?
No. Pay-per-action ads are not eligible to show on Google.com or in the Google search network. They’re only eligible to display in the Google content network. Source: Pay-per-action beta — your questions answered

Wow, I would guess a lot of advertisers will skip the PPA test because of this, anyone testing it yet? They also say they are only taking people with US mailing address.
