Is there any way to develop XNA games and disable the inherent game loop?

I am working on a Windows-only 2D game that is "event" driven (like Windows).  The game will only need to re-draw and/or update when actual user interaction occurs (mostly key press and mouse click events).  I would only need to animate/move the sprites in the game after a valid action was performed.

For network play, the game would only need to update when a client successfully performed an activity and the server notified everyone that the activity occurred (i.e. a "Player Did X" Event).

EDIT:

Never mind...I found what I was looking for here:

Thanks!
