If a USB mouse is declared the core pointer, X won't come up without it, AllowMouseOpenFail notwithstanding. If it has SendCoreEvents set, xmodmap pointer = ... will no longer remap its buttons, as it only works on the primary pointer. xmootmap is a bare bones command line tool that lets you remap buttons on secondary pointers, and is aimed at laptop users with funky mice. Intended use is mostly from ~/.xinitrc.
Xnetintf is an X Windows application that manages network interfaces. The current interface state is depicted through a series of bitmaps, and a mouse click in the window initiates a state transition. Xnetintf uses a per-interface configuration file to supply commands that check and toggle state, as well as a program to run after the state change completes. A command line interface is also supported.
