Wouldn't you still be limited to two sizes of image in your scenario? We're not talking about a vector-graphic-type scaling, right?
It's a step in the right direction, however. We need some kind of auto-scaling image format. JPEG2000, perhaps? I've never worked with them, but I believe they're supposed to include "in the image" or somehow, size accommodations. Just more food for thought...
