Thanks for this info.  I've gone the path you suggested and added a  
"CID" service.  At present, it provides access only the Registry/ 
Ordering/Supplement for CFF CID fonts.  What's the best way to  
integrate in the FreeType sources (assuming you're interested in it)?  
I can post a patch in the usual way through the bugtracker at  
savannah, or follow any other process that's more convenient.  It's  
not a huge diff, so a patch might be sufficient.

Thanks for your help,
Derek
