Microsoft gives users the green light to test-drive Vista diskless, virtual set-ups

Microsoft is expanding the avaialble pool of Windows Vista licensing options yet again, by offering new diskless and server-based virtual licensing options.

Microsoft officials say they aren't expecting customers to flock to these configurations, as they are designed to appeal to very large enterprises with very high-speed, reliable networks. Watch for financial services firms and some governement users to be among the early adopters, the Softies say.

One other caveat: These new licensing options are only available to Software Assurance volume-licensing customers.
