How to make a Flash IP to IP application, for sending a media?

Without using Flash Media server or other media server for flash. How is it possible to send peer-to-peer packets straight? Can we send direct packets from one point to another?

I have tried with Red5 and realized it is horrible to do quality of packets switching by involving media server in the middle.

Yes, it is possible

First take a look at Cirrus; which is Adobe's Solution. It uses Real Time Media Flow Protocol (RTMFP); which I believe was introduced in Flash Player 10/AIR 2.

If you google a few other options come up. Here is one tutorial.
