No, plain ole' rsh. But I get the same result with ssh.

Working with a 100MB file and doing a null sync, I see:
rsync --stats -e ssh -a --block-size=64000

I ran rsync --stats on two identical files of size 100MB with a 64KB
block size and extrapolated to 20GB. The files themselves are
incompressible.

If I'm counting correctly, 20GB
Ok, I think I figured out how to combine the algorithms.
Start with a base (like 8 or 256) and a minimum block size (like 256
bytes). The improved rsync will use the old rsync algorithm as a
subroutine. I'll call the old rsync algorithm orsync and the new one
irsync. Instead of actually transm

The recursive algorithm which does a binary search for changes works like:
1. If the size is smaller then 128 bytes
then send it over
else Each side does a strong checksum
If they are the same, then do nothing
