Thanks Diane. At think point I don't think it will be worth it to try and use SVG - due to the performance changes on different devices. Perhaps when someone codes an efficient, pre-compiled, SVG renderer it will be acceptable to do so. I don't like the thought of working in Flash, either (when it's released). So I'll wait until SVG is supported more efficiently.
