IHMO, it would be VERY BETTER to store in dbase (MySQL as first candidate, I
think), in this 
case you may not trouble about hash, will get right rolling back (in case,
if dbase support transactions), simplify administration, GUI clients,
backup/restore ...

But, I admit, translating tree structure of projects to tables will eat 
more (I presume very more) space and performance then build same over FS :(.
For me it's 
along reason, why converting cvs to dbase is problematically.

Comments?
