Guys, please, calm down. One of the points of the new IC is to make MP a fair play.
This mod, which I was unaware of before, runs outside of the scope of the IC. It uses the Export API. We have a server-side option to allow/forbid world objects export, but no option to control the ownship export, just because it was assumed to be safe.
So, talking about LEAVU-style mods, this is a simple question of adding a server-side option to allow/forbid ownship export. If I understand you correctly and this is what you want - the option will be added soon - it is relatively simple to implement.
