psyced is a multi-protocol gateway and server application supporting the PSYC, Jabber, IRC,  and more protocols such as HTTP. It performs as a node in distributed synchronous conferencing and instant messaging networks such as PSYC and Jabber. A special feature are its programmable chatrooms with the ability to multicast content to other PSYC servers and the users connected to it. PSYC uses its own multicast strategy on top of TCP and UDP to achieve that. psyced can be used as a replacement for a traditional IRC or Jabber server. It is available under the GPL free software license.
