Silverlight 5 - How to implement mouse-look camera?

Is it possible to create a 3d first person perspective game with Silverlight 5?

Java applets can do it: for example Minecraft game using OpenGL. WebGL can't do it: see How to implement mouselook in the browser? question.

It would require ability 开发者_JAVA技巧to capture mouse: a) get relative mouse move every frame b) force mouse cursor to stay inside game window.

It's probably impossible but i'm posting to get attention on this problem on google search.
