Jabber-based server and client application in Cocoa

I have implemented an application which currently supports text chat. 开发者_开发问答Now I want to implement voice chat and later video chat in it, but I have less time provided by client. :( So I am planning to go for some open source code in Cocoa, which I can use and easily incorporate into my application.

After analysis on the internet, I found that a Jabber-related client/chat server application should be best according to my requirements.

I have found that there are several Jabber-based client-server applications but they are mostly written in Java, C, or C++ and are not Cocoa-oriented.

Can anyone suggest me some links or code for a Cocoa-based Jabber server and client application?

Also I want to ask that let's say I have a server application built in C and a client application built in Cocoa, then will I be able to transmit text and multimedia messages between client nodes?

in xmpp no generic support of media transfer, but you can use xmpp as signal channal to establish media session (see jingle for example)

Leapfrog is using the PSI-Core.

Would like to see some progress.
