At this point there could always be another filesystem flag. From recent 
traffic I think that ReactOS might wind up with something other than FAT or 
NTFS as a base filesystem. Whether it winds up with something like Ext3+Posix 
ACL's or a custom brewed filesystem is up to whoever is doing that work, but 
one could have an ACL on files for that permission or, in the case of the 
custom brewed filesystem, an actual permission in the filesystem.

Truly, though, I'd suggest ReactOS try to implement an NTFS driver, since NTFS 
already has the capability (as of the Win2000 version) to seemlessly compress 
or encrypt single files, directories or entire drives.
