The open-source project shadowing Silverlight has come a step closer to mirroring the latest edition of Microsoft's challenger to Flash. Moonlight leader Miguel de Icaza said a preview of Moonlight 3.0 has been delivered for early testing. Features include early work on UI virtualization to handle large sets of data, and a platform abstraction layer that separates Moonlight from the windowing system engine and should make it possible to port the player to windowing and graphics systems that are not X11/Gtk+ centric.
