We were discussing that in the office today. It's got promise (for us,
anyway - I'd be surprised if it got much traction on the web any time soon)
but needs the alpha channel work completed at the very least. Progressive
rendering would be nice but it's not vital - we can provide the benefits in
other ways. Having another channel we can use for bump maps would also be
very helpful.

Another format referenced in the discussion is JPEG-XR (originally released
as "HD Photo" by Microsoft, now an ISO standard), which has all of the above
features. It might be worth doing a comparison, bearing in mind that
compression/quality ratio is not the only thing we care about.
