Hmm, those are actually pretty good.
Wish I could take credit, but this it's Ian Bell and David Braben's canon, I'm just applying it to this particular situation in a consistent way.
... except that CMDRs can telepresence into them from their own ships, potentially several KLY away. See what I mean about consistency? it's a real quagmire. I do like Paramemetic's lore fix though.
Fighters
were in a tricky spot in lore, because they would FSD into CZs when canonically the Eagle is the smallest fighter that can fit a FSD. With SLFs this is no longer a problem - they launch and are telepresence controlled from the ship that you're controlling.
When you telepresence to another person's ship as a Pilot's Federation CMDR, consider it like a relay: your telepresenced man relays from that ship to the SLF. His actual physical body is still sitting in his own ship, but through the same kind of VR that enables Simgurus and Arena and so on, he telepresences and holoprojects there. From that ship he relays his projection into the fighter.
NPCs, not having PF Licenses and therefore not being CMDRs, are not allowed to telepresence like that but must, due to PF regulations, be physically present on the ship. CMDRs, as literally one in a trillion unique, powerful people, are allowed to do that thing.
Seems like it works for me. v0v
Edit: It is killing me,
killing me that you guys are talking about shortwave radio standards and bandwidth limitations in a spaceship video game where galaxywide instant data transfer is just straight up "this is a thing that exists."
