Here is the project site of xsim(X Simple Input Method).
xsim is an input method server for Linux and FreeBSD, i'm not sure it can run on other type *nix.
By now u can input chinese in X Windows System using pinyin, wubi, cangjie....
you can download the latest version of xsim source here
the last version is xsim-0.3.9.4
I will not create any binary packages myself, i'm too lazy. but someone help me and build some for xsim.
Here is the latest
xsim_0.3.9.2-1_i386.deb (made by pastebt)
xsim-0.3.9-TLW7CN_1.i586.rpm (made by linuxrat)
Any question mail me firstname.lastname@example.org
