Hole punching seems inflamatory to me.  This is just typical innovation, 
the same kind that brought you NAT.

I wouldn't call a NAT box a firewall.  Nor would I call iptables a 
firewall if you only used the NAT table.

And for all the admins out there trying to block Skype, an article that 
discussed how to do that and what the implications were to other 
services would have been much more interesting.
