Ok, now we are getting into the nitty gritty of things, and as I said in my video, I dont have all the answers, especially when it comes to powerplay.
Let me be absolutely clear, I do not want this to be an arbitrary system just to keep everyone safe, and all the big bad meanies in a corner, because that dosent make for a fun game at all.
What I want is to give a realistic effect to open where those who commit random acts of murder against 100% innocent commanders, in relatively safe systems, face consequences for their actions. And to deter that kind of activity any further.
Anyone who engages in PowerPlay is NOT 100% innocent in my books, and entering enemy territory is just asking for trouble.
Lets use your example.
If the beluga is part of an opposing power that is not currently in control of that system, but your power is, then that beluga is 100% fair game, blow it up, how DARE it enter your system, such cheek!
However if the beluga is part of a power that is in control of that system, and your invading that system killing their ships, then you gain negative karma in that system ONLY. You would basically become KOS for local security and stations.
If you are both in a system that belongs to another power that you are both non aligned to, then I would say you would both be ignored, or whoever open fired first, would get a small karma decrease, but still be able to land at the station.
BUT, if that beluga is not aligned to any power, then you gain negative karma across ALL systems. How local security and stations treat you is based solely on that systems security level.. Anarchy and low security would mean no one cares about your karma level, wheras higher security systems would interdict you on sight.
Obviously this would need some balancing, but I am sure a group of relatively smart people could work something out..
I dont want the Karma system to be so draconian that anyone engaging in PVP is going to be heavily penalized.. But I do think those going seal clubbing, or hanging out at CG's just for quick thrill kills should face heavy in game consequences.
How exactly that is done is going to be one hell of a task, but I think something needs to be done, especially to help new players get a little bit better at the game.
I dunno.. maybe thats a bad idea, but I think you can sorta get the gist of my intention.
