Cool, plus it'll be more fun to roleplay swapping tech and stuff. All part of the challenge.Not sure, I 'spose they could do a tight band subspace transmission, but didn't want to invent something not already seen. So got any ideas? Would morse code work?I'll try to stay up a bit longer so that we RP stuff if need be

Morse code would be harder to identify as a method of communication or be decrypted, since at that point it would be obscure and old, like radio. Might be worth a try, but it would be like waving sticks to them. :p
