From The Digital Reader:
Amazon got a lot of attention earlier this week with news broke that they had been awarded a patent for a “used digital content” marketplace. Many took it to be a sign that Amazon was interested in creating used content market similar to the one they maintain for books, DVDs, and other physical media.
Naturally this has the blogosphere and tech industry intrigued, but no one was more interested than ReDigi. This 2 year old startup has already launched a marketplace where US residents can resell music they bought. It went into a public beta in October 2011, but only currently supports music purchased via iTunes.

[From a ReDigi press release]
ReDigi’s advanced technology employs a “Verification Engine” and “Atomic Transaction”, resulting in a TRANSFER ONLY mechanism. This means that all digital goods are first verified to ensure that they are legally eligible for resale. Once verified, ReDigi’s technology transfers the “original” good from the user’s computer to ReDigi’s Cloud (Marketplace). With ReDigi’s method, only the “original” good is instantaneously /atomically transferred from seller to buyer without any copies. ReDigi then assists the seller with an anti-virus like software application that monitors the seller’s computer and synced devices to ensure that any personal-use copies of the sold good are removed.
Just to be clear, ReDigi want to install an app on your computer so they can make sure to delete any copies of a song you sell via their service.
