I was thinking of something like, the ID's are there but they don't show up when you are scanned. unless it's the admins who scanned you. Yes, I do see the flaws in a system like that. But it does make it possible to take out that Metagame.
(Yes I count Wilde/Covert Ops ships being ID'ed insistently regardless of the IFF as Metagaming, there's no way your character would know that unless you are a Nomad or a member of the same Covert Ops branch)
Again, it does need a lot of work and refinement to make it work, it's just a concept at this point, but I think that's the direction the game needs to go down.
