I haven't used rsync Josh, but if it is easy in the Terminal, then it
will be easy in Rev. Just call the same shell commands you used in the
Terminal.
As an example, if I want to get a detailed directory listing in
Terminal, I use:   ls -la
In Rev, I would use:  put shell("ls -la") into fld "Listing"

I see from the man page that rsync does both local & remote file
transfers. Can it be used to do uploads to a web site instead of FTP?
It seems that the web host would need to be running an rsync server
and I have no idea whether that is common or not.
