No. This is wrong. You can use views to restrict users to view only
programs they want to use, the needed shared libraries and some devices.
But you can't enforce an even stricter view (e.g. only the documents) since
the applications just won't work anymore.
Such a strict "filter" belongs into userland applications and only there.

We have quite a few things [or will have] which could make good use
of extended attributes. Nobody volunteered yet to part it :)

I'd like to use EAs for security related features, but there quite a few
other uses as well.
