Well there other probes as hackers or something i think that feature wold be useful...for secret agents.
And the thing about the other contacts has to have msgplus also its not a probe if its your girlfriend or something, or if you really want to encrypt the message and the other part too there is no probe about installing msgplus.
I dont see the need of that because the logs can be encrypted and hackers... bah who wants to see the convo with your grilfriend?
And..the echelon well they dont care about that eheh.
