I'm sure someone has.  I'm sure those people also realized what a *huge*
security hole it would be, and how much it thrash the server if it was
implemented in a "safe" way.

There is a well-known way to provide access to external shells
(command interpreters) in any moo, or any mud for that matter,
with no server modifications.

Write a program that logs into the moo as a player, and sits in
a room waiting for people to come in and say, for instance,

To restrict access to it, restrict the room as you would any other.
