The problem is to fit the x-ray pulsar into the spacecraft without a) killing
everyone and b) collapsing the spacecraft under its gravitational field :-)

Why xray pulsars?
Millisecond pulsars have shown themselves to be very accurate - wouldn't an
ensemble of those be a better choice?

I suppose that Jim refers to receive the signal from the already
avaliable and conveniently fitted ones (at a safe distance from the
spacecraft and users :) ) instead of having one on-board

I think it's an energy/flux density thing. you need a big antenna to
detect the millisecond pulsars.. bigger

It's NASA's job to push technology. That was half the
reason for the moon project.
If we get a $5 10-14 XO we'll find a use for it, no?
