Moonlight: Silverlight For Linux

The open-source Mono project will show off an early version of Microsoft's Silverlight browser plug-in running on Linux later this week.
Work on the plug-in, called Moonlight, was started only in May, after Microsoft's Mix conference. Moonlight uses version 1.1 of Silverlight, a browser plug-in for displaying interactive Web applications, which is due in the fall.
Once completed, Moonlight will allow Linux users to see Silverlight content on the Web, such as videos, and run rich Internet applications.
