Let's be careful here. Rsync *does* work on 1GB+ files. What you
probably meant to say was that rsync's first pass might fail on
files that have 1GB+ of changes. But the second pass (which uses
the full MD4 block checksum) will work correctly.
So a more correct statement is that Rsync might work *slowly* on
files with 1GB+ of changes because two passes are required.
BTW, rsync already has an adaptive block size unless you set it
on the command-line. The block size is roughly
min(16384, max(700, file_size/10000))
ie: file_size/10000, but no less than 700 and no more than 16384.
