Well, over the last half hour, I've had a bit more time to think about
this. (On a side note, I've been thinking about a research proposal for
a Masters in Engineering, and I'm considering putting this in.)
By using a reasonable block size (1-2K), one should be able to do a
series of comparisons (either lossy (by way of correlation) or lossless
(direct comparison)) and store only the blocks that have changed. It's
basically the same thing as streaming video uses for compression. But
in this case, there would be no real-time dependency. But it should be
relatively quick...
