KMuddy is a MUD client powered by KDE. It aims to be the most powerful, fast, feature-rich and easy to use MUD client.

The current version already offers many features such as powerful external scripting (which supports very many languages such as Python, Perl, Lua, C/C++), and it's own internal scripting. It has split-screen scrolling, command history, buttons, gauges, logging (both in plain text and HTML), multiple connections, regex support (on both aliases and triggers).

All in all, KMuddy is a very powerful competitor among MUD clients on Linux already, and we're looking to expand to Windows and Mac platforms with the coming of KDE 4.
