Hi Tim.

 From my tests, arcfour produced a noticeable speed increase.  I was 
digging around trying to find the numbers, but couldn't find them.

Also Harry will need to figure out what is good enough for speed. If I 
am doing frequent replication, then mbuffer makes a lot of sense, but if 
I am backing up a couple of times a day, then most likely an SSH 
connection is good enough.

I also compress data through the SSH connection, but since Harry said he 
was on a LAN compression wouldn't make sense.
