good question Andy... right now i've got casual chat working, and have it so that you must be in the same compartment in order for the chat to show... someone in the conning tower couldn't chat with someone in the ward room...
the Captain can announce over something similar to the 1mc shipboard pa for fixed, general messages...
alarms are also broadcast shipwide...
specific items, like sending a target bearing to the XO from the scope are right now voice overs "bearing, mark... one... nine... five" and the XO has to work his plot... these are not sent over the 1mc, and are only heard if you are in that compartment...
i've still got a lot to work on, a lot that keeps changing... but inter ship communication is pretty much down pat...
just a few kinks to iron out... it seems as if there's always a few more kinks to iron out
