Unless Juergen's object is "code-like", IOwned is a distraction;
ownable objects exist only to prevent trojaning (as Chris correctly
pointed out earlier).

I don't know why you would say that. The "Owner" local role (as opposed
to executable ownership) is widely used to allow creators of content to
edit it in places where they would otherwise be unable to do so.

It *is* possible to hijack the role computation here; getting it right
is tricky, however, and when it is wrong, your error messages are going
to be inscrutable. The "right" place to do this might be in a custom
user folder, rather than in content. PAS, for instance, has the concept
of making the role computation for the *user* pluggable.
