Are there any plans to implement multiplayer, even player-run server support would be amazing.

I don't think that is a good idea.
The game would need to be fairly redesigned for multiplayer to be a useful part of the gameplay. Sure, you could have people running around on the map, having a look at hash-codes or trying to track down a blip on the radar - but from how the game looks right now, it is certainly not designed with multiplayer in mind.
None of the tasks the player do in game requires more than you, the player to do them. And none of the tasks the player can do would be helped with multiplayer in mind - with the potential exception of figuring out where a radar contact might be.
If there are plans for Multiplayer, I hope they wait with it until they at least implement solid groundwork for it.
