Production system that would chain-ssh through various bastion hosts to get around asinine firewall systems, eventually telnetting in as root to a non-standard port to run a script and dump data out of the files on disk of a MySQL instance backing a virtualization system. Billed based on how many of the output files that instance appeared in ("hourly billing!"), and who was the "owner" of that instance.
