"SE4 already has such an intel project,"
Really? It gives the content of the message as well? As in, "I will invade Kartogia IX while you attack the other side of the warp point to Urteka"? I never knew that. I've been playing so long without intel, I don't even remember ...
"and it's minimally useful as players can communicate outside of the game... 
"
Well, yeah. That does ruin the plan completely.
But maybe vs the AI, if they can give more complicated mssages, it could come in handy.
