Remote Tech Frequency Mod request

[StormxWolf]

Hello fellow kerbonauts, me and some friends have been playing a Dark Multiplayer game (which, I want to say has been working surprisingly well as of late) and have sort of delved into this sort of game of rivalry. It's gotten to the point where we rent communications time to each other on communications satellites. This works fine and great so long as we aren't using omnidirectional antennas as you can imagine. For those that don't know there's no way to target or filter what the omnidirectional antennas will and won't connect to. So I had a creative yet somewhat lore friendly idea in mind: is it possible to create a mod that can set frequencies for antennas such that those antennas only connect to other antennas with matching frequency. A bare bones mod would simply add the functionality to omnidirectional atennas however for a larger mod you could add it to all antennas.

TL;DR friends and I are playing war games on a dark multiplayer server, need a way to limit what remote tech omnidirectional antennas and dish antennas (when pointed at a planet) can connect to. Had the idea to implement this in the form of satellites can only communicate to satellites on the same frequency.

If this is hard to do, could simple filtering be possible? Filtering like basically generating a connection whitelist.
