You have reiterated exactly what I expected would be one of the most popular
reasons to want to implement a JVM for the RCX.
I hope you don't think I'm against what you're attempting to do... it's just that
I, like Kekoa, believe that the endeavor you are about to undertake may transcend
the limits of feasability. There is not a lot of room to play around with inside
the RCX, and Java was developed in an age where memory limitations were largely
being looked at as superfluous on account of ever-diminishing memory costs. I
believe that it may make a JVM for the RCX impossible, or at the very least
impractical. I'd like to be proven wrong, of course.
