As i wrote in another mail, it is clear that the user account is far less a good
sandbox as it was earlier. In particular, the same hole exists in X itself, potentially
affecting all X-clients which bridge into another domain of rights.

Nevertheless, that a program cannot escape the boundaries of a user account
is a usual and valid assumption. To lay yet another escape path is not a good
idea, imo.

To leave the general consideration, what are the intended uses of the feature?
When the feature was removed earlier, it was limited to send a 'cd Dir' (where
Dir is a proper path name) to allow konqueror to control an embedded konsole,
which clearly is much harder to abuse.
