Hi,
Lots of propositions have been done, how about this one:
A file with meta-data is a simple 'tar' file, i.e. uncompressed. It works for cp, mv, backups.
A file with meta-data like ACL is protected to everybody (chmod 700), a suid daemon will take care of the ACL before giving the file content to an authorised user.
An executable file with meta-data is just wrapped (binfmt or something like that) to execute 'tar -x filename.tar ~/tmp/filename; ~/tmp/filename' using tar magic number.
A data file with icon-type has just one soft link included in the .tar, pointing to ~/.icon/myicontype .
And the only kernel related thing, mounting a meta-data enabled filesystem is managing tar file creation on the fly when you do a 'ls' or a 'cp'.
Is that more than $0.02 ? Etienne.
