My thought is that if the new spriting technique degraded to showing a single image (a button, for instance, with no hover state, etc.), then that would be a pretty reasonable fallback. I think that would be the ideal to hope for. Thus, a multi-layer PNG that looks like a regular PNG of the top (or maybe bottom) layer would be good, if such a thing was possible. Of course the whole ZIP archive idea sidesteps the problem by NOT being a new spriting thing, but rather just a new delivery method. That would be VERY backwards compatible, just not as nice, IMO, as multi-layer support.
