There's a reason companies use security clearances that include
background checks and references, system and data backups, and the
threat of lawyers and litigation, right? All that is probably easier
to manage than explaining to a customer why their systems are offline
for an unknown period of time...

Mikal: thanks for the tip about the SSH authorized_keys file. Remote
commands will work even with an invalid shell? How?
