in so far as ssh is just one of dozens of commands that the girls learn on the command line, it's perhaps not.

in so far as it makes them realize that computers are discrete entities that are networked and that this is what the internet actually IS... it's priceless.

The first time we connected to a remote machine in a different state it BLEW THEIR MINDS. One of them asked if it was EVEN LEGAL :)

It's a single command, yes, but it's also the pivot point for a whole unit on remote access, networking, IP addresses, etc.

So consider SSH shorthand for that whole subject.

I think if ssh is really just "time with a command line" then it's a super valuable exercise. You can remember none of it and still go away with the lesson that the CSI looking thing really ain't that complicated.
