User setup, IP and access controll

Hi Anton,
To prepare a possible setting like that, where at the users can be set let an IP address be permission, that let him be able to step from only a particular IP address onto the user's own surface? On a server side it's possible, but like this other user exclude where dynamic title distribution yes. Other question, that possible modification like that, where at the users single entitlements, settings let him be allowed to be singly to allow or to prohibit. Pl. let new geofence be able to record an area, but let him be unable to delete it or to repair. Thanks, Zoltan
