This sounds reasonable. I imagine we'll be using the EmbeddedJava API for
this, as this allows us to implement only the parts of Java we need or can
support in the RCX. I'm a bit disappointed with the minimal info that
java.sun.com provides on what the EmbeddedJava API is. I mean, it says that
java.awt.applet is unsupported, everything else is configurable, with
configurable being (by my interpretation) "pick and choose for your platform".
We'll likely need to use LegOS as our base, as actually implementing a native
Java machine is, sorry to say, beyond most.

Actually, we can't do EmbeddedJava since that requires a full JVM including long and double, the Security manager, etc. We aren't going to be able to call it Java, since it won't pass the compatibility suite (we can say it implements a subset (...)
