Well, that didn't take long. eBay has added Google Checkout to its list of online payment methods not permitted for use on eBay. Obviously eBay wants you to use PayPal for all your online auction needs but, instead of saying that, they claim Google Checkout lacks a "substantial historical track record" as an online payment service:

Google's spokesperson said yesterday, "Google Checkout is not a beta product. Google has a long history in billing and payments for AdWords and for premium services, such as Google Video." Two multi-channel eBay-management services announced integration with Google Checkout - Marketworks and ChannelAdvisor. Both worked with Google during initial development and testing. But eBay sellers may not accept banned services on their customized eBay checkout systems, according to eBay spokesperson Hani Durzy last week.
