What is the output of the NXT graphical programming environment? I mean the NXT
could already have a JIT type execution environment already whereby the
graphical IDE generates pseudo-code ("bytecode") and the firmware on the NXT
does the dynamic translation on the fly. I don't know, but the above *seems*
reasonable to me. Moreover, future versions of the NXT compiler within the
graphical IDE would be compatible with any platform changes (new JIT firmware).
Right?
I wonder if the specs for the firmware and/or feature set will be open (i.e.
Lego will publish complete/specs, etc. during its release).
