XMPP协议与jabber目前工作jngle的感想

XMPP协议是对IM的语义的很系统的总结，但是也只是对于消息本身和用户列表本身而已。很多即时通讯工具被视为天经地义要有的附带功能，文件传输啦，语音传输啦，甚至p2p的文件共享啦，都没涉及，而没有这些，即时通讯工具简直没法混。这些要求催生了一系列新的jep-XXX的协议，现在最火的就是对于jngle的讨论了，

JEP-0166: Jingle

This document defines a framework for initiating and managing peer-to-peer sessions (e.g., voice and video exchanges) between Jabber/XMPP clients in a way that is interoperable with existing Internet standards.

但是说真的仍然相当不完善。

最重要的是如邮件列表里这位大哥说的一样：

I don't agree with it. It took a lot of time to get a decent, working, implemented in many clients file transfer protocol. Do you remember the time we had several incompatible file transfer protocols? Do you really think the advantages of the new file transfer protocol are worth moving back to that?

In Jabber we need working, even if not perfect, protocols for the features people want. We still don't have good (working and impelmented in many clients) avatar protocol. We still don't have good protocol for voice communication between two Jabber clients (not IP telephony, just simple voice communication -- that is what users want. Jingle is still work in progress). But we have more and more new, more and more complicated protocols nobody uses... Jabber was good as it was simple, now it goes the way H.323 and SIP (SIMPLE) went... I don't like that.

我觉得主要的问题还是，现在的硬件水平进步使得很多应用的设想都变的可能了，于是新点子就极多而不象以前那么吸引人。http协议其实就很简单，其主体就是从MIME来的。在用户要求越来越多样化的今天，keep it simple and stupid 简直是最难的考验。
