Peter Saint-Andre blogs about Jabber’s 11th anniversary and what the focus will be for the XMPP community during 2010. Here’s his list:

• End-to-end encryption
• Finalizing Jingle-based file transfer
• Multi-user Jingle for voice conferencing and the like
• Distributing chat rooms across servers
• Bridging between serverless mode and server mode (very useful in distressed networks)
• Reputation systems for XMPP servers and users

All of these issues are important. End-to-end encryption is something that the SIP community should spend more time trying to handle and I can only wish for some cooperation between SIP and XMPP in trying to find a security architecture for end-to-end communication - involving both encryption and authentication.
