Your browser's next plugin: Silverlight?

At this year's NAB, Microsoft has revealed Silverlight (né Windows Presentation Foundation Everywhere, WPF/E), its new cross-browser, cross-platform video plug-in. This new plug-in supports Safari and Firefox as well as MSIE and was written using .NET technology.

TUAW reader Neil points out that this means that at least some of the .NET framework must have now been ported over to the Mac. You can read more about the introductory post here on Tim Senath's Microsoft blog and Neil's .Net on Mac analysis here.
