I have to imagine this has been suggested already, but with the million or so local threads, reading through them would be onerous at best.
What if you could have ships hack local? Same hacking mechanics, with whatever level of difficulty it should have. I’d want it to require high skills and a hacking fit ship.
Since it’s the gates that provide local channel, you hack an outgate and it disables updating of local from that gate for 15 seconds from the time the hack completes. Counting session changes, that’s just enough time for a gang with a good prober to jump in, scan something down, and fleet warp to it.
Would be limited to sovnull to increase our risk, where it is frankly too low at the moment for the rewards of being in that space.
Programmatically it would require new code, so there’s a definite developer time cost to this one.
