The Extensible Messaging and Presence Protocol (XMPP) is an IETF standard that provides a complete cross-protocol messaging solution. The problem with current IM solutions is that they are all proprietary and cannot talk to each other. XMPP seeks to get rid of those barriers.

Net::XMPP is a collection of Perl modules that provide a Perl developer with access to the XMPP protocol. Using OOP modules, it provides a clean interface for writing anything, from a full client to a simple protocol tester.
