Let's not go forgetting that different factions will have differing levels of technology.
All my ships, for example, use radio transmission. No video, no teleporter or anything sci-fi. My Marauder isn't even pressurised, requiring me to be in a spacesuit with an oxygen tank stuffed in the cockpit.
I can talk to other people and accept transmissions across whet ever bands my equipment can pick up. White, blue, green and pink.
As for neural net, I think of it like an online banking system. "Neural Net" Is just the catchphrase used to describe the system. It holds my credits and I can backup information there. It's an alliance of various civilian banks and information agencies to cater to the needs of the space travelling public, for a profit of course.
Truth be told I've never really considered the Mission Commission to be a giant neutral organisation, rather being the comms tower of whatever station I've taken the job from.
