Is there a way to run an xna game from a web page without installing anything? Something similiar to java, silverlight or very close to a wpf browser applications (XBAP).
Scenario:
Go on webpage, Get asked to install
the game. Game installs, game screen
shows up in webpage. Can full screen,
etc.
The game is a full blown xna framework game, using 3d, has access to the system calls such as directx and other low level networking api. This is probably more of having javascript working with windows system if anything.
SilverSprite seems to do what you want. I have never used it but see XNA 2D games come to the browser via Silverlight.
