hi Steven, you're completely right,
in fact I want to some more: also taken hardware and physics into account.
You can see one of my first demo's here, to see what I mean:
   http://stef.mientki.googlepages.com/jalspy_demo_robot1a.html
and some more demos can be found over here:

In fact we already used the simulator a number of times in real 
applications with great success,
but didn't release it yet, because you still need Python knowledge to 
run it reliable.

Yes, right again ;-)
The simulator translates JAL into Python,
In the beginning I thought that was the easiest,
I'm not sure about that anymore at the moment,
but on the other hand that's just replacing one module.

Yes, Paul also pointed me into that direction,
and to be honest, I expected there would be such a module,
but I never searched for it, because ....
If I see that I can cook dinner,
when I (very seldom) test the program  (I'm writing) in the debug mode,
(assuming the IDE uses the same pdb),
then this is far too slow :-(

I'll report back what my experiences are with pdb.
