Skype uses the "accidental" topology of the network as the platform for its addressing. How else does it do it? But because Skype assumes its users are likely not to have static IP addresses Skype has a way to route to these users. It's P2P meshing is not a consequence of this but a necessary party to making this possible.

There is also a potential cost to this as anybody who uses Skype through a firewall knows as you open up undefined ports to unknown hosts.

It would be so much easier to establish application level addressing schema's including for Skype type services over an end to end underlying addressing architecture. Being able to program one's way out of trouble is clever but it is intelligent not to have to.

You don’t want static IP addresses – that’s like putting a concrete
base on your cordless phone. Look at Skype as an example – it creates
its own stable addresses without tying them to the accidental
topology of the network. You get P2P meshing as an accidental byproduct.
Where I do agree is that local traffic tends to be local and peering
is a business relic not a technology.
