Using P2P, Flash sites will be able to serve higher quality video than YouTube at a fraction of the cost. Meanwhile, the combination of the Speex audio codec and the Real Time Media Flow Protocol (RTMFP) will enable sites to seamlessly integrate VoIP without requiring a Skype install. The impact of this change is hard to fathom. We’re talking about a fundamental shift in what is possible on the Internet, with Flash demolishing almost all barriers to integrating P2P on any site.

Check out Adam's LittleShoot p2p platform:

LittleShoot is the most powerful transmitter I can imagine. After working for four years as the lead engineer at LimeWire, I started LittleShoot to overcome all of LimeWire's shortcomings, from ease of use to legal issues to the underlying technology. The result is a standards-based peer-to-peer application that works directly from your browser with the most powerful searching, publishing, and downloading technology available today.

LittleShoot is far more than just a powerful transmitter. It's also a receiver, and it can find new signals. In many ways, it's like Google for files instead of web pages, but that doesn't cover the transmitting. With LittleShoot, publishing your content is clicks away, and you don't have to wait for it to upload anywhere.
