UDP NAT P2P

这是一个P2P聊天的程序，基于ＪＸＴＡ框架，ＪＸＴＡ框架是一个比较简单的Ｐ２Ｐ框架，利用ＪＸＴＡ开发P2P相对来说比较容易，不会给程序员造成太多的负担。

大名鼎鼎的agobot，是自己写ircbot一般需要参考借鉴的源码-The famous agobot, IRCBot are generally required to write their own reference from the source

一个很典型的p2p应用，这个是客户端，服务器端正在上传-A tipical application about peer to peer. This is the client, and the server is uploading.

详细介绍emule协议，可以参考p2p开发

P2P无中心设计，在没有任何固定服务器的情况下，人们仍然可以畅通无阻的进行点对点的交流，传输文件，语音，视频等-P2P no center design, in the absence of any fixed server circumstances, people can still smooth conduct peer-to-peer exchanges, transfer files, voice, video, etc.
