The question in my mind is how do you define those "parts".  If it's 
something easily restricted to a given set of Piccolo directories, then 
may be fairly easy.  If I understand correctly, that's how OpenROAD 
could release its 4GL code as open source without releasing the 3GL 
pieces which for the most part live in other Piccolo directories.  We 
similarly "removed" spatials from Ingres DBMS open source, because most 
of it was in common!adf!ads.  However, if you look at change 469243 
where you removed B1 security support, you had to touch (edit) 380 files 
all over the source tree.  Conversely, although I don't know much about 
Project D, I'm guessing that would affect various areas of PSF and QEF.  
There is therefore a high likelihood that changes will affect existing 
directories and existing files, i.e., not neatly separable "parts".
