Well, to be true, i have examined the system, but under which permission
programs a co-owner? under permission of himself?
That is not the goal of making things MO.
But when you grant people  permission to hack under permission of other
people, they are infact a wizard over the .owner of that  object. You don't
want that either...

I have setup a grouping system, with a general owner (child of $prog, with
a playerbit), who owns every object (eg, all objects within a theme).
When programming/editting, verbs will run under permission of the objects owner.
In this way hacking on other people is not possible..(and preferable above
the other system)

Builtins which are frequently called, have an alias on #0, where the check
comes in case of such an object....
(My english is bad, i know, don't mention;)
