There was a mod, many alphas ago, that had in it (as a part of a bigger mod) a machine that when turned on would increase the % of orbital trade ships, at the cost of also attracting mechanoids. The more it was turned on the more attention it drawn, to the point that mechs and ship would became really really common and you needed to turn it off for a while. It had a cool texture if memory doesn't fail me. I have absolutely no idea of the name of that mod ... it was a long time ago, but it was soo cool. I miss it ::)
Sounds cool... and useful!
If I had the time I'd have a go but sadly I don't really :-\
Yeah

It don't got the risk of Mech/pirate raid's but you need to craft/buy a transponder.
