Depending upon the distribution of file sizes, his limitation may end
up being disk seek speed rather than raw network bandwidth.  Moving
lots of 4k and under files will take more time (and not saturate the
network) than moving a bunch of 4GB video files over.

Plus, given linux<->linux, he can just run rsync and let it take care
of everything.

And/or use ssh+tar:

tar xjvf - -C sourcedir <files> | ssh destmachine tar xjvf - -C destdir

Very true.  And for a one-time transfer this is often the better route. 
Paying attention to whether one should, or should not, add a / at the
end of a path to get rsync to do what one wants is not always worth it
for a one-time transfer.

Rsync, however, will win out if one ever wishes to synchronize changes
on the source over the same path to the destination a second, or
additional, number of times.

If things don't go well with that pipeline, drop the 'v' in the
option list.  Don't know for sure about current GNU tar, but I
have seen tar versions that would intermingle the file names from
'-v' and the data stream, which would cause things to go sour on
the receiving end.

There is also the 'trick' of using a tar archive to move the files, since the 
tar archive will preserve the Linux filenames, owners, and permissions.  The 
name and permissions of the tar file itself are not going to be important.

By the same token, I use zip files when moving between Linux and
Windows systems.  Time stamps are preserved, and line endings in
text files can be automatically converted (LF vs. CRLF).

Thanks you (and the OP) for the reminder. Archives can indeed be our friends.
