JamochaMUD is an open source MUDMuck client written in Java. JamochaMUD offers Unicode, plugin, and multilanguage support to allow a more enjoyable MUCKingMUDding experience. It features command history, synchronized window controls, experimental SOCKS 5 support, and greatly improved ANSI colour support. It plays nice on Unix systems, supports a wide range of MU*s, and also includes emulation of some TinyFugue editor controls. JamochaMUD will use either Java 1.1 or higher versions automatically, and includes classes to be easily reused in other Java applications. Systems running later versions of Java will have more features available in JamochaMUD.
