Is there a security spec that is above MIME etc.
For a company it could be interresting to give people rights on certain
MIME types. I mean like the group users is not allowed to play mp3 files
and is prohibited to write on a cdrw but is allowed to read it (this
would need a media spec).

Interresting would also be (for the utopia project) to be able to not
allow certain groups to mount usb sticks (usb sticks form a easy way to
save secret info, could be a security risk for some companies)
