You could ship SVGs and lazily generate PNGs for the specific device. Once it's generated, you keep it cached. Although it might be a little slower on the initial run. I guess it depends on your SVG's complexity. Webkit does a fine job with SVGs. You could draw it on a <canvas> element to get a rasterized view of the SVG in the desired size, and save the resulting image.
