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 access to the XMPP protocol. Using OOP modules we provide a clean interface to writing anything from a full client to a simple protocol tester. WWW: http://www.xmpp.org/
