Hi All,

I am working on an application where I like to bundle 3 things: 1. Chat 2. Audio / Video Conversation 3. Desktop Sharing

I would like to know the approach and where to look in for this, few of the things that I am aware of are:

1. Chat and Audio – I can go with Jabber server and configure any SIP server like asterix for audio calls.
2. Desktop Sharing – I have read about silverlite coming up with Desktop Sharing modules, but what would be only targeted to Windows. I would like to have sharing for windows, mac and linux OS. I don’t mind building separate clients for each. But I like to know which common protocol has to be used for Desktop sharing. In other words something similar to team viewer. Please suggest.
3. Video Conference – I totally don’t have any idea about this.

The application that I am supposed to build has to target the below platforms: 1. Window, Mac, Linux Desktop 2. iPhone, iPad and Android Devices.

Would appreciate any help or reference or links to any of the topics (Chat, A/V and desktop sharing).

Thanks Ravi
