Yes I agree, a writable NTFS would be useful _BUT_ it's not likely to
be very good for backup/restore because the security information would
be wiped by the process.  The only way I could see it working is to have
a program that goes down the tree creating a .aclinfo file in every
directory that has non-default permissions on one or more files in that
directory. You backup all the files then on restore have another process
that puts the acl infomation backup where it belongs.  Obviously this
needs a little support from the filesystem driver.
