IRCG: XML Real-Time Streaming
IRCG is a revolutionary way for dispatching messages to huge groups of users over an arbitrary number of separate communication channels in real-time. IRCG provides message streams over persistent HTTP connections and can interface with a subsystem to produce static file snippets. All aspects of IRCG are scriptable using PHP. IRCG is format and content agnostic, and can produce any output format you require, including XML, XHTML/HTML, and WML.
