How crazy is your friend?  What's wrong with a cleanup PLL?

As Bruce said, the people I know of who are good in that area are the radio 
astronomers.  They need timing (phase) stability rather than just frequency, 
so their problem may be harder than yours.

Beware: time sink alert.  His references are fun reading.
