What is Amazon's Unpay?

I came across an interesting article today on TechFlash where the reporter has noticed that Amazon is seeking to trademark the therm 'Unpay'.  He speculates that it's a refund feature, but I don't know that seems like a stretch. Why would you trademark the term you use for refunds.

Over on eBay Strategies, we have a couple of Paypal news items in the payment world.  One area Paypal is really spending some effort on is mobile.  So my guess is this is a new mobile payment system coming from Amazon. 

According to the whois database, unpay.com is registered to a Tom Adler under private registration at network solutions.  I checked and don't see any Tom Adler's working at Amazon.

What do you think? Let us know in comments.
