InterNetNews is a complete Usenet system. The cornerstone of the package is innd, an NNTP server that multiplexes all I/O. Newsreading is handled by a separate server, nnrpd, that is spawned for each client. Both innd and nnrpd have some slight variances from the NNTP protocol. WWW: http://www.isc.org/products/INN/
