While it's true this doesn't make any use of the rolling checksum,
because rsync gets so many other things right in its file transfer
algorithm I found it easier to just slightly extend rsync than to do a
more major extension to scp (for instance, I want files to only be put
into their final place when they're complete, which means that the
tool needs to be able to write out a temp file to a different
directory and then move the completed file into place when it has
fully arrived). It was easy for me to add an erase option to scp, but
I haven't yet attempted to add a tempfile option to it.

Yeah, that would be safer. I think that "--move-files" is a pretty
good name for the option. Let me know if you'd like me to whip
something up for you (or feel free to tackle it yourself, if you
like). The 2-line code fragment (plus "extern" line) I sent last time
is really all I needed to add outside of the option parsing/passing
code.
