Today, KDE's Konsole terminal window has a "ZModem upload" function,
which I've used for sending a file up to some system where the
administrator on the remote machine has disabled scp and sftp for
random security $REASONS.

I could compress the file and use uuencode/uudecode, but for larger
files where cut and paste isn't terribly convenient, using zmodem can
be one of the simpler and more effective.
