Time synchronization between spacecraft might take advantage of 
pulsars, reducing the bandwidth used on inter-craft comm links. As 
frequency sources, they are as good as Rb short term, and as good as Cs 
long term. It should also be possible to use pulsars in a GPS-like way, 
for position and speed.
