Interesting points about network architecture:

But as I think further last few weeks, he might have a point. The Internet today is no longer the end-to-end network we original envision. Thanks to NAT, firewalls and private IP address, writing an applications today for IP network for end-to-end communication requires a lot of tweaks and hacks, and eventually some sort of overlay network. The most popular applications in the last few years, such as Napster, Kazza and Skype all have ways to 'overcome the NAT' or 'bypass the firewall' in order to achieve end-to-end.

Services like Skype could not exist unless the network automatically makes decisions for you in this area of assembling routing paths throughout, and through your machine. This decision making is neither good nor bad - it's just something users should be aware of, and, consequently either consent to or not.
