// we know the length of the roundtrip: it is 2x the light lag. progress bars show a passage of time,
// it could scroll:
// * along the bottom of the message
// * across the message
// * as it is being sent, a transluscent red bar grows from right to left (towards their messages)
// * while we are waiting for acknowledgement, a similar blue bar brows from left to right
