>From my current experience, you are definitely on the right track with 
approaches along those lines. I would just replace the word "all" by 
"chunks" or "bundles". "All" is going too much toward the other extreme. But 
"bundles" is a good compromise and the bundle size can be adapted to the 
available hardware.
