I agree, it's not really batch but you get the same ability for a job on
one machine to automatically run a command or command procedure on another
machine.

It's also better than batch in some ways in that the ssh session will not
terminate until after the command has completed (successfully or otherwise)
so if you invoke the command procedure directly from ssh, you get built in
synchronisation between machines instead of having to work out when the
batch job on the target machine has terminated.

VMS does have proper batch queues, but you cannot submit jobs remotely to
them from a Unix box on a standard VMS system without using ssh to do it.
