Any online marketplaces that allow trading of gold?

[TheOraclePaul]

Hi everyone - I was just wondering if there's any online marketplace like Ebay that allows bartering of services or goods for gold/silver. I know goldmoney.com lets you transfer funds in gold/silver, but it's not exactly a 'binding contract' to deliver a service or good, like barter would be. Let me know, as I think something like that would come in handy in the future.

So more of a payment sysstem with an escrow service.
