On its own not much, though it could combine with other things.What's the exploit? What's the advantage they have over stashing a 'conda in a FC and logging off?
Head out to distant X in a ship, docking only at megaships/FCs (Colonia Bridge makes this easy for some routes), do stuff with the ship out there.
Use the megaship escape pod to return to your home station, switch to Horizons to instantly get your ship back too.
Similar to the prison taxi but without so much dying. So ... probably more than nothing but not enough to be worth bothering about.
Best actual exploit I can get out of it is:
- get an Anaconda, lightweight it as much as possible, big fuel scoop, rest of the optionals passenger cabins. Range is still over 50LY.
- start in a Colonia system at a conventional orbital or surface port, pick up 10 famous explorers at 50M each for tourist beacons in the bubble
- fly to the bubble, docking only at CB megaships to repair FSD (technically "unsafe locations")
- scan the beacons
- dock at a FC/megaship, escape pod to the mission source station
- switch to Horizons to get your ship back too, hand in the missions
Should be possible to do the whole thing in under 4 hours, for >125M/hour. But it's a lot of effort and there's easier ways to earn more than that even so.
(Equally, if just in-game time is counted, there's 28 days realtime to do the missions so you can already go both ways while asleep on a carrier and get ~500M/hour for the logged-in hours if you're fast enough on the tourist beacon circuit)
