With IRCG you can rapidly stream XML data to thousands of concurrently
     connected users. This can be used to build powerful, extensible
     interactive platforms such as online games and webchats. 
     IRCG also features support for a non-streaming mode where a helper
     application reformats incoming data and supplies static file snippets in
     special formats such as cHTML (i-mode) or WML (WAP). These static files
     are then delivered by the high-performance web server.
    
     Up to v4, IRCG runs under these platforms:
     
AIX
FreeBSD
HP-UX
Irix
Linux
Solaris
Tru64
Windows
