One idea that comes to mind for me is satellite operations. With the SSB sats 
I can see one Rx locked to a beacon frequency. Given a known beacon frequency 
and known transponder freqs/conversion ratios it should be possible to find a 
place on the downlink (with a second Rx) and then have software place the 
uplink in the right place (and keep it there). With this approach you if you 
are using omni antennae you wouldn't even need recent keps. The math is out 
there but this would stretch my modest talents. I don't have the skill to go 
much past the concept stage with a project like this :-).
