It seems to me that the solution to this is to precompute the block checksums on the server. We'd have an command like "rsync --gen-checksums FILE1" which would create a FILE1.rsync-checksums file that the server could read. If you wanted to do it recursively for a whole tree, just rsync -r --gen-checksums /path/to/dir. Given a beefy enough server that can keep all the relevant files in the dentry cache, I would think that would take care of most of the overhead...
