At one stage I was SUPping off sun-lamp to a machine at work, and then
running a script I wrote on the output of sup -v that generated a
shar file that I took to home via a disk and then ran that shar file
on my source tree.
This script correctly handled file additions/changes and
file/directory deletes. I haven't used it in ages though; for a long
time I had my netbsd box in at work directly on the 'net, and recently
I got an EXB-8200 for home so I just take a tar file home when I feel
productive and want to play around with -current :)
Here's the script. It may need some work.

Usage: $progname [-u] file
parses the output of a 'sup -v logfile' and generates a shar file
containing the commands to get its source tree in sync.
-u `Updating' lines are considered `Receiving' lines.
(when the log file is of a 2nd attempt and you
already had 1/2 the files.)
