I think that Sun will retain rights to the name "Java". So, if I
release a Java applet, by definition I expect that level of
compatibility. If Red Hat forked and created there own version, they
would have to call it something different. The problem you describe
is still valid, but I don't think there will be end user confusion
about what I expect them to have installed on their system for the app

Ok, so now we have to go a little deeper. There are Applets and then
there are JApplets. Applets use AWT (the Abstract Windowing Toolkit),
which is how Java pushes native components. The reason why every
Applet you've seen looks like Motif (or Tk-ish), is because Java was
really using Motif widgets! This didn't change until Java 5, and now
Applets push GTK+ widgets. All that aside, AWT is limited and
everyone recommends Swing. JApplets use Swing not AWT. There are
many good looking Swing applications and Java 5 or better JRE's
emulate the Windows look perfectly. GTK+ emulation is darn near
perfect in Java 6. There are many good looking Swing apps, any one of
which could be converted to be a JApplet. Maybe I'll make a sample
one and post a link for everyone to inspect and give some feedback on
(if you're willing to install the Java 6 plugin) :

Oh ya. I don't think that this would displace the technologies you've
listed. This would be more convenient for those who are more familiar
with Java (or desktop software development in general) than web
development. I doubt web designers are going to want to stop
producing prototypes in photoshop and start making them in NetBeans
designer (though they might?).

Capability wise, I think that Java 2D (the stuff that backs Swing) is
right up there with Flash. But animation libraries aren't as mature
as Flash. If you want to do animations, then you should stick with
Flash. If you want to make a rich application, JApplets are better.

True. Good post, good points.
