Screenmodes smaller than 640x480 ?

*edit*
My original question was regarding screen sizes smaller than 640x480, but I've realized that the t2dSceneWindow's size can control how a camera is scaled and displayed...
like if I have a camera that is 320x240, and the t2dSceneWindow is 640x480, it should scale up..
or if I have a camera that is vertically oriented, 240x320, I'd use a size of 360x480 on the t2dSceneWindow...

But I'm still wondering if it is possible, or will be possible, to rotate the t2dSceneWindow, or basically the main surface that everything is getting drawn to..

I'm wanting to be able to allow the user to rotate or flip their screen to work with however they are playing, it would be for a vertical shooter, so some people like rotating their monitor or flat panel, or maybe even running it in a vertical arcade cabinet... Also, the ability to simply rotate the surface that everything is drawn on could be cool for general purpose effects.
