Microsoft has a new preview web site entitled “Windows Marketplace Labs” to showcase new methods of buying and selling Windows software. The first such effort is called Digital Locker. Digital Locker is a method of purchasing and downloading third party Windows software online, and then using that purchased software on any computer you wish. This is handled through Microsoft’s Passport authentication service, the same system that is used to identify your Hotmail account, MSN Messenger settings, and other Microsoft services such as MSDN.
