not sure how many people need to copy big sized files over to remote boxes over the internet and how frustrating it is to get connection stalled and timeout right after 89% of copy has completed. scp doesn't support partials, however rsync does and can save lots of time recopying over unstable link, i.e.:
$ rsync --partial --progress -a --rsh=ssh --bwlimit=100 *.rpm [email protected]
is the same as
$ scp -l 100 *.rpm [email protected]
except it will resume from partial upload.
