Cryo pods haven't really been discussed much, though they are obviously going to be implemented (what sci-fi game doesn't have cryo pods?). Another thing that hasn't been discussed in much detail is spawning, quitting, and sleep. I suggest that cryo pods would be like a tier-2 bed. When a player chooses a cryo chamber, he/she will always spawn in that pod, no matter its position, so no spawning in empty space and losing all your power cells!
Sleep in a cryo chamber could take you through hyperspace quicker (if everyone is in their pods). When a player disconnects, his/her skin will appear in the pod so another player doesn't claim it (if that's at all possible).
