It would be a really worthwhile project in general, and it could be
made very general with very little trouble.
I would find a cheap ARM board (Olimex ?) that can support ChibiOS:
http://www.chibios.org/dokuwiki/doku.php?id=news
and add a "cape" PCB with a high resolution DAC for EFC control
and two phase detectors, one for 100kHz-20MHz frequencies and one
for 1-100Hz frequencies. (The latter could have a TVB PIC divider
as an option on the reference input).
Maybe add a couple of isolated distribution amp outputs also ?
That would make for a really experimenter-friendly computer PLL
platform.
People who want to code can do so, people less ambitious could
tweak PLL params in the default firmware using the ChibiOS command
line interface...
Count me in...

Never attribute to malice what can adequately be explained by incompetence.
