It would seem that with in the streaming of information that moves across networks, that such things as virus detection within these networks(meaning governmental oversite of info...post 9/11), which, if I'm not mistaken is regexing for matching strings of definitions, are checked for as they stream through systems, leaving mainly encrypted versions for release. That way, even if they don't stop it, and watch it propagate(to see what it does), then they still know you weren't a part of it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
