I would think that ebay and paypal would just use the same method to curb scamming that they use now temporarily on new users, where the funds are not released to your account until the goods have arrived at the buyer's address through a tracked shipment or expected arrival date. I see them simply requiring a similar or a manual confirmation for all BTC transactions in perpetuity.


Also/more so I see papal allowing you to fill your paypal balance with BTC that is in turn converted to your native currency for your paypal balance. Which if so could become the easy way to convert BTC to fiat in your checking account.
