Sure! IIRC, newbies got a brief welcome guide when arriving on Thisavrou explaining how they got there/how things work; they could have something similar on their devices. My one quibble is that since they just arrived on Avagi themselves, I'm not sure how much information they themselves would know to include besides "Welcome to Avagi, it's a space station, we don't know how we got here and we don't know how you got here either" xD

And yes to the music players, as well, though that might mean they'd have to work out earphones as well :P
