[e2e] Skype and congestion collapse.

[Alex Cannara]

Syed, the misconception is that apps are to manage network resources.  That's 
not how more robust systems, like the established telco and private network 
systems work.  Systems must protect themselves, even a car's gearbox, from 
external abuse.  The Internet is only different in that attention wasn't paid 
to doing that in its design.
