IP Convergence: Beyond VoIP, Beyond Cost Savings

Although, to balance the point, if shaping mechanisms like Caspian's did (or do) become successful, the applications will evolve to get around them. Skype already has crafty ways to get through firewalls. There would be a game of cat and mouse, a little like the anti-virus vendors, as the P2P and VoIP vendors attempted to stay ahead of the QoS guns. The difference is that network's change at a much slower rate, so it wouldn't be a daily update. It will be interesting to see how this evolves though!
