Owen's and Michael's cache icon theme information as presented on the 
xdg-list, should help that a lot, AFAICT; it's a binary index(mmap'd etc) 
where the names are hashed, and can contain the images too(all in one file). 
But perhaps it's not a possibility?

I think also Nikolas Zimmermann had plans about an "icon server", or 
something.
