folk do not always get the implications of the internet being a
'disruptive technology,' and that this is a good thing which needs to be
preserved and even enhanced. they use skype and want to block ports.
it's rampant. the old siliness of blocking tcp/53 is just one of the
corner cases that keeps popping up publicly. try using this year's crop
of innovative apps from behind some corporate firewall. packet/port
xenophobia overrides the users' desire to be productive every time. it
departments are paid to minimize cost and risk, not maximize workers'
productivity.
