I wouldn't mind a security pane in the general configuration
for the master backend which controlled this and other security
related things. But I don't think it is a significant security
risk. If an attacker has access to any of the machines on which
MythTV is running she has access to the local network so she
has almost complete control over MythTV via the MythTV protocol.
Since any sensible MythTV installation on a networked computer
has neither the backend nor the frontend running as root the
compromise would restricted to the capabilities of the user
accounts under which the MythTV components and mysql are running.
