 近期计划：
-1. 支持IPv6(100%)
-2. 支持随系统自动启动，安装成系统服务(100%)
-3. 提供一些免费服务器给特别差的网络，如广电网络(100%)
-4. 建立网站，用户可以在网站管理所有P2PApp和设备。查看设备在线状态，升级，增删查改重启P2PApp等(100%)

 5. 建立公众号，用户可在微信公众号管理所有P2PApp和设备
 6. 客户端提供WebUI
-7. 支持自有服务器高并发连接
+7. 支持自有服务器，开源服务器程序
 8. 共享节点调度模型优化，对不同的运营商优化
 9. 方便二次开发，提供API和lib
 10. 应用层支持UDP协议，实现很简单，但UDP应用较少暂不急(100%)
 11. 底层通信支持KCP协议，目前仅支持Quic；KCP专门对延时优化，被游戏加速器广泛使用，可以牺牲一定的带宽降低延时
 12. 支持Android系统，让旧手机焕发青春变成移动网关
 13. 支持Windows网上邻居共享文件
 14. 内网直连优化，用处不大，估计就用户测试时用到
+15. ~~支持UPNP~~(100%)
 
 远期计划：
 1. 利用区块链技术去中心化，让共享设备的用户有收益，从而促进更多用户共享，达到正向闭环。

-7. Support high concurrency on server side.
+7. Support private server, open source server program.
 8. Optimize our share scheduling model for different network operators.
 9. Provide REST APIs and libary for secondary development.

 11. Support KCP protocol underlay, currently support Quic only. KCP focus on delay optimization,which has been widely used as game accelerator,it can sacrifice part of bandwidth to reduce timelag. 
 12. Support Android platform, let the phones to be mobile gateway.
 13. Support SMB Windows neighborhood.
 14. Direct connection on intranet, for testing.
