No it wasn't an instantaneous idea.
I have a prototype CDU "panel" (made from paper, overhead transparencies
and transparent contact paper). 

Check out X11GC, a x11-based glass cockpit software I'm working on. 
Thats whats gonna drive my CDU. But for the logic behind it, the FMC, 
it'd be nice to have a standalone program... :)
the X11GC page:

two CDU screenshots:

but freely downloadable. I plan on making some under the GPL)

Well, Nasal doesn't fit too well in my "standalone" concept. I already
have a scripting language integrated into my X11GC/PHCC* programs (They
share some classes, and can be built into one binary).
I use LUA, an embedded scripting language.
Easy to learn and easy to integrate into your own programs :-)


*PHCC is my cockpit electronics interface solution:
