I love the concept of reselling your digital assets. Bought a bunch of songs you no longer care for? Resell them. Ebooks you've read and have no use for? Resell them. The used CD and bookstore model that works in the physical world will definitely be a vibrant component of the digital content world.
I've written about ReDigi before and today these pioneers of digital content resale have some terrific news to report: theyv'e been awarded a patent for their unique method of "copy-less" digital content resale. You can read the whole press release here but this is the key excerpt:
ReDigi’s patented technology provides significant opportunities to unlock the full value of digital content by creating a system and method for the resale of that content without actually having to make a copy.
Selling "used" digital content is a tricky concept for some people to accept. After all, an MP3 or an ebook can be copied endlessly, so how can there be a single version of it that can be sold by me and bought by you?
I believe ReDigi has the answer to that question and, more importantly, we'll all be reselling and buying much of our digital content through ReDigi (or ReDigi-powered services).
My biggest hope now is that someone like Amazon doesn't come along and swoop these guys up. After all, reselling digital content shouldn't be locked into a walled garden.
