Diomidis Spinellis writes "Microsoft's Windows Marketplace Labs offer a
preview of their Digital Locker technology.
The Digital Locker uses Microsoft's Passport Network to allow Windows users to search, buy, and download software from multiple retailers, storing their product keys for future installations.
Both retailers offering the service support digital rights management technologies:
Digital River promotes its SoftwarePasport, and
eSsellerate its Product Activation technology.
Will this technology trigger an across-the-board adoption of DRM for Windows software?
How will it affect the distribution of free and open-source software?"
