It would be interesting to see how compression would do if pushing
across a slow link :).
There are many times where I run across the OP's scenario, but often I
need to push a tar across a relatively slow link. bzip is slower to
compress, but may make up the difference in transfer time. Maybe time
to fire up maxima and find that sweet spot :D
