Thanks for the response -

I gave a win32 port of xdelta a try. Locally, it works great. 
However, going over the wire, it is another story.

Example. I have a 134MB file on one computer, connected at 10MB 
ethernet to another.

Copying the file takes about 90 seconds.

changing about 10 bytes in the file and running an xdelta takes about 
140 seconds and uses a ton of bandwidth which is what I was trying to 
avoid. I can't imagine it over a 256k frame relay.

I guess without the program running on both ends and talking to each 
other like Storage Replicator or NSI Doubletake, I don't see a 
command-line solution to it. Unfortunately those (as well as any 
internet-based solutions) require a ton of cash for an environment 
our size.
