eBay bans Google Checkout

As expected, eBay has banned sellers from using Google Checkout -- the new online payment system which will compete with PayPal. eBay has added Google Checkout to its unapproved payment methods. I'm not surprised at the ban. PayPal is a huge source of revenue for eBay and I can't imagine them opening their doors for Google to swoop in and take a large portion of their income.
