yes, tough you don't want to use command port for that thing. Because you want batches launched by the os, and that in all essence is not hard. That is if you really run your own mail server. But yes things like procmail are easy to set up.
But you can use it to remotely fix some users, rig or something else, connecting devices is pretty straightforward so thats one use.
Hell if you really want you could run a web server on maya, pretty expensive one tough.I frosted a example of this few days ago.
