I`m bored at work, so this is my proposal:
Introduce a new module: high slot, cpu/pwg as a cyno, duration 10 minutes, requires Liquid ozone to function (with an associated skill to reduce consumption, like cyno), gives the ship an weapon timer and puts it into siege.
What it does: every server tick (1 secod) pulses on 50km AOE and cargo scan ships in the AOE. The results (estimated cargo value in ISK) will be displayed on overview (needs new column) and on ship label in space.
Extra option (dependent on a secondary skill): u can set a cargo value threshold (lets say 1 bil) and if it identifies such a ship, will broadcast it to fleet. Also puts an overlay big red arrow towards the identified ship with text “This one! SHOOT!”.
Extra extra option: sends the identified ship a flashy red message: “Oh man! You did it again!”
