There's a half dozen serial ascii commands to the CSAC, and a 
corresponding number of output messages. None are particularly "special" 
- I can't imagine needing a "display" for the telemetry, except perhaps 
as a novelty.

You'd want to periodically check the heater power, maybe?

I'd just expose a "diagnostic interface" on a CSAC based clock, and if 
you want to fool with it (or change the frequency, etc.), you hook up 
your external whatever.
LE Bluetooth Serial port perhaps?

You could write an App for a phone to talk to it, and I'm sure it will 
be in the top10 on the iStore and GooglePlay within weeks. Your 
retirement funding is assured. <grin>

Very much so. Even here on "time-nuts" we discuss more about "frequency" 
- ADEV is a frequency error measure, after all.
