If we go that path I'm afraid we'll end up with a horrible mess of several  
incomplete client-side and server-side solutions clobbered together with  
preloader-killing scripts.

The closest thing to what Ian is suggesting is <x-picture> implemented  
with <img postpone>, but due to standardization failure it won't be able  
to benefit from image preloader or offer users/UAs ability to control  
image selection.

Basically authors will hate us. We've been going in circles for a couple  
of years now and all we have to offer is an incomplete solution? And  
browser vendors can't even agree which one of the half-baked solutions is  
it going to be :(
