Oh yes, crap...I forgot about that one. I ran the app under IRIX
(1.3 JVM) and it ran fine, once I got the serial I/O working.

Eh. I admit that, when they first came on the scene, I thought they
were a great idea. But the technology stayed so immature for so long,
I just got turned off to the whole idea. I agree with your point about
kiosks, but that is a pretty vertical application.

Yes, that's great...but (and I know you know this already) there's
nothing preventing people from doing exactly that with ANY programming
language. It is hardly an exclusive feature of Java; it's just that it
really hasn't been implemented with many other languages. (there have
been some...the ancient UCSD P-system comes to mind)
I think they're making a huge mistake by trying to tie the two
concepts (virtual machine and the Java language) together so tightly.
Many people (indeed, MOST people, even some people here!) don't
understand that "Java" doesn't necessarily mean "virtual machine".
I've actually had people tell me that I don't know what I'm talking
about when I've explained that to them. Morons.

Absolutely. There have actually been many of these built. Many are
in use in the embedded world, and Sun has even produced one.
