Just in case you missed the news, Google Checkout is live and it looks pretty slick. It is really for B2C/B2B - in other words, paying merchants, not for P2P transfers to friends. Right now it is only for US merchants, and they only accept Visa, Mastercard, American Express, or Discover credit, or debit, cards. But that's a pretty good start. Looking at their merchant implementation options and API, it is pretty slick. It looks solid.
