Silverlight is Microsoft's rich Internet application (RIA) platform and competes with Adobe Flash. Moonlight 1.0 passes all of Microsoft's regression tests for Silverlight, according to project lead Miguel de Icaza, vice president of engineering at Novell, which sponsors Moonlight.
Moonlight is only available on Linux and Unix, but is otherwise interchangeable with Microsoft's Silverlight 1.0 plugin, de Icaza said.
Much of Microsoft's recent RIA strategy has focused on features specific to Silverlight 2.0, and particularly its line of business controls. The Moonlight group plans to preview its 2.0 release at MIX09 in March and come out with a beta in the summer, with the final version hopefully ready by PDC, de Icaza said.
In the meanwhile, Moonlight is already improving the Web for Linux users who have until now been unable to watch WMP videos, de Icaza said. Microsoft is providing its codecs to Moonlight, meaning that Moonlight applications can play WMP files. One such application, Moonshine, presents itself to Firefox as Microsoft's Media Player plugin, meaning that Linux users can use it to view Windows Media content within their browsers.
