Integrate a Google Talk Jabbar client in to LibreOffice buisness communications application accessable in Writer.
I don't see the point of integrating a jabber client into LibreOffice... Could you give some use cases that could help to understand your request?
Integrating an XMPP client just for communicating is a no-go for me as we have already clients on the desktop doing it very well.
Please add this to this wiki page instead: http://wiki.documentfoundation.org/Development/Crazy_Ideas
Please do reopen this bug if you have actual code that implements the requested feature. Then we can reconsider.
