Remember the rumor that the Zune will pay you for sharing a song that someone ends up buying? Well, that rumor was squashed by Cesar, the pants wearing blogger last week. Not so fast, says a reader who uncovered a whitepaper from Microsoft detailing their possible foray into "off-line economies for digital media."
In the paper, Microsoft details a way for one user to sell content to another while giving profits back to the copyright holder but still compensating the seller for participating in this offline economy. The paper also talks about adding Bluetooth to an iPod device, immediate purchases on-the-go, sophisticated sales scenarios, and best-effort anti-piracy DRM restrictions. I've had enough fun reading white-papers to last me a life time, but if you're interested, hit the PDF link.
