What sub sims could use........

[John Pancoast]

.....ala flight sims for years.

The ability for two or more human players to man different posts online. Communicate via voice comms software, etc. Different player as captain, navigator, weapons, etc.

Flight sims have had this ability for years, i.e., pilot/co-pilot, etc.

Seems like it'd be a hoot in subsims too.
