First off, very cool. I agree that you should use very small maps. Maybe even set a detail level in the options or something.

Have you been able to generate the environment map from the center of the reflecting object with it being hidden yet? I was asking because I noticed in the screen that the sphere was reflecting itself.

Have you tryed setting this to refresh every second or so yet? If so, what kind of effect did it have on fps?

Good luck. This could possibly solve some of the problems of not having render-to-texture in the lower editions.
