....what linux naitive MU* apps are out there? I'd rather not install wine just to get my text-based gaming on.
The most singularly powerful classical MU* client is TinyFugue. http://tinyfugue.sourceforge.net/
It compiles on virtually every machine known to mankind. It's pure text/curses based, so will run in an xterm or on a serial dumb terminal. It's very low bandwidth, and can be run remotely over dial-up links. It has a full array of macros and scripting to allow almost any level of complexity and automated actions.
For a graphical interface, try Trebuchet http://www.belfry.com/fuzzball/trebuchet/
Trebuchet is based on TinyFugue command syntax, but wraps a nice GUI around that.
Both these are staples on the 30 or so machines I use for doing Internet rooms at various conventions.
