Yeah, I'd think this isn't really a problem that should be solved as
part of HTML5 but rather as improvements to the protocol level.
Spriting is after all just a hack around the strict 1-file-1-request
nature of HTTP and not something that's really fundamental.

For instance theoretically SPDY should solve this problem. Or indeed
so would HTTP pipelining, if it was used more often.
