This point in this thread seems as appropriate as any to mention
syndaemon. It's part of the synaptics (now xorg-x11-drv-synaptics)
package. When it runs, it disables the touchpad while the user is
actively typing on the keyboard and re-enables it after a brief pause
after the user stops typing. Sounds very neat. (I haven't felt the
need to actually use it, as I don't have too much trouble with
accidental tapping of my current touchpad.)
It does require setting SHMConfig, though, so that problem still needs
to be addressed.
