Could you consider putting the signature of the file that needs permission? I use the signature as a way of figuring out whether it is a safe or not.
Similarly you could provide a right click in the Computer and Network SecurityPolicy list for a quick assesment when one wants to check at a later stage. Or like Process Explorer from Sysinternals provide the signature by default; with the possibility to leave out the Microsoft signed ones.
It is currently not possible to let the list of Computer and Network Security Policy be sorted out by application name. That makes searching harder.
Keep the good work up. (B)
