Fast, encrypted file copy

From time to time I need to copy files between UNIX boxes without having NFS, SMB, whatever in place. This can be easily done with SSH, TAR and, if available BUFFER. The needed command is:

tar cvf - source-dir/ | buffer | ssh -e none -c blowfish user@remote.host.tld "cd /dest-dir && buffer | tar xvf -"

If BUFFER is not installed, simply remove it and use:

tar cvf - source-dir/ | ssh -e none -c blowfish user@remote.host.tld "cd /dest-dir | tar xvf -"

instead.
