I will definitely look at it.  I have also discovered that Sun did some
experimenting on a GUI toolkit called Truffle which was optimized for use with
displays like touchscreens:

For industrial machines like CNCs, it seems like it would be a good idea to
control them with touchscreens but I will need to research this further.

Also, I am going to experiment with using uVM for providing the implementation
for a realtime JAPL 3 Axis motion control peripheral.  I am finding that coming
up with well-thought-out JAPL peripheral specifications is quite a challenge
but even at this early and crude stage it looks like this technology is going
to be a winner.

The other candidates for the implementation are:

- An 80X86 based realtime multitasking kernal I developed a while back.  About
5 years ago I used to kernel to concurrently control 12 stepper motors on a
large filter wrapping machine that I helped build for a company.  I am very
interested to see how a 100% Java based system compares to this kernel because
it was written in pure assembly language.

- TimeSys's newly released RTSJ compliant JTime.

- A JStamp or a JStik but to be honest I have been holding off doing any
serious development on JStamp or JStik until Ajile releases their CDC/RTSJ
software.

My initial work with uVM, though, leads me to believe that it will up to the
task.
