Hi Ralph,
the hardware is ready to take off :D

What are your plans to release Beta-4-Preview with improved I2C-Support ?
The world wants to use pbLua and not NXT-G or other stuff :-D
One real world scenario is "helping handicaped blind guys". No joke, I have to
friends, who are blind and want to play with Lego-NXT.
They are using a braille device and a screen reader to control the PC. NXT-G
with graphical interface is impossible, but using NXT with pbLUa and a simple
terminal is possible!
The first project with pbLua was a simple color-reader (more grey or darkness
detection) for blind people, yes it worked!
Now we want to try out a simple blind-men-stick for distance detection...
NXT isn't just gambling or waste of time!
Handicaped people love it to investigate some time in research of new
technology. pbLua is a milestone for using NXT-Robots!

I have to write it here, because your SPAM-filter didn't like me ;-(
