Yes, an X driver capable of understanding the kernel/mtdev protocol is
needed in order to translate to the X world. In Natty, we achieve this
by modifying evdev to translate to the XI2.1 protocol.

The mtdev library will be needed as long as there is hardware and
drivers using the type A protocol. It can also be used for hardware
testing. It is not likely to go away anytime soon.

The above. It would be very interesting to hear about your
applications, if you have something to share. :-)

Thanks,
