Yeah, that article is crap.  I like how he states that Skype "pursuades" 
the firewall to let it through.  Bah.

Can we please kick people like this out of our industry so people don't 
think computers are "black magic" and "voodoo"?

No wonder customers have no idea what they want.  People like this lying 
about how the techology works so they can have a "security" title on 
their website.  Sad.
