But this wouldn't allow to do any changes in a defined grace period
after the files where placed on the share.

- Is there already a module that does something similar and can be
easily adapted to provide a kind of WORM feature? I saw
source3/modules/vfs_readonly.c, what maybe could be an entry for a solution.
- Can this be done by some who is familiar with C? Or should it be
better done by someone who is Samba code experienced?
- Do you guess it's much work? 1, 2, 3 weeks,...?
