I've already done a lot of the work (on a separate program that I use for
testing).  The only thing holding me back right now is that currently my
driver relies on the fact that the touchpad sends dummy packets for a
time after you have moved your hand away from the pad or released a button.
This allows one to use those packets for timing purposes.  The Linux kernel
thoughtfully suppresses those packets, so I need to use timer calls instead.

I don't know much about rights management.  In order to access an extension
you have to have an X connection, and there are ways to restrict which users
can connect.  That's the only restriction in place right now.  However, if
someone can connect to your server, then they can clear your screen, etc.,
so I don't see any access issues with the extension that you wouldn't also
want to apply to X connections in general.
