Hi, Efforts are going on for boost asio based libraries for different protocols. It will be intersting to have a XMPP library in Boost. I have done some experiments with existing xmpp libraries, include libjingle-4.0 from Google. Moreover I have analyzed design issues involved in XMPP. I will like to start the project by developing "chat model" for xmpp. Alongwith that, I will keep on developing codes for jid, roster, message buffer etc. Some of the key things will be:- 1. Message dispatch --- this I will address using spirit's actor concept. 2. Since sequence in which messages are delivered is vital here, so we need to have a xmpp scheduler. 3. Seamless integration of different application to basic framework, like integration of chat/audio/video application to basic framework. This in turn means, development of the idea of basic framework--- like what will be its parts, how to attach applications to it, etc. I will like to set up emphasis on developing xmpp library which can be used for many applications.
