The source code is available from
        http://pfaedit.sf.net/TtfMod/
I'm not distributing built versions because
  a) it doesn't work well yet
  b) these run up against Apple's patents and I want to leave that 
decision to the
        users.

Sadly this will never be. PfaEdit is too entrenched in postscript. but 
ttfmod will do this now.
PfaEdit wants to convert things into its internal format but figuring out 
what hints are implied by truetype bytecodes is essentially impossible and 
different "hints" may be in effect at different point-sizes.

Not really. How do you count subroutine calls? How do you deal with the 
'prep' and 'fpgm' tables? How do you compare 'cvt ' to BlueValues/StemSnap?
