I think you are making a new interpreter sound harder than it really is.
The standard firmware might not be incredibly fast, but it certainly
supports multithreading, and synchronization wouldn't be hard to add. The
only challenging thing to add, mainly because it requires forethought, will
be variable support. And the majority of the work will not be adding
better variable support but instead duplicating the functionality of the
current firmware, for which we have pseudocode to possibly use as a guide
but no source at this time.
I (still) think porting the JVM and making it usable is a harder task than
bringing up a custom, RCX-specific byte code interpreter. If you (you
being anybody reading this who disagrees with me) think you have the
knowledge and the capability to port the JVM and hack it to interface
nicely with the RCX, I urge you to prove me wrong. The proof is in the
pudding, I'll believe it when I see it, the devil is in the details: they
all apply here.
