the silverlight live video player (Microsoft.Mix10.UI.Silverlight.xap) used in Mix10/VSLaunch events is very nice !
but I really want to request an important feature: out of the browser and always on top !
because I always need to browse the web (searching, downloading, discussing the just-released good stuff ),
or even try some cool tricks and features in visual studio, then the video player embedded in a web page goes behind and become useless,
it will be nice if I can make the player 'always on top', and silverlight 4 OOB does support the Window.TopMost property, so please take advantage of it
