	Thing with the Thunderbolts is not all revisions of the
firmware seem to play nice with ntpd.  And yes, the PPS is quite
narrow and would have to be conditioned as well.

	I think I'd start somewhere else unless you also needed
the frequency reference.

	Good news is, the 2100-GPS used a 5-12VDC antenna with
no downconversion, so it should work with just about anything.

	Randy, what's your budget for this?  ($$$$ and space)
Does it have to be 1U, or is a 1U GPS receiver and 1U time 
server acceptable?
