Linux -- unsure, if there is, it is Alpha 2
3.1 -- no, there is no threading support
'95 -- not yet, Sun apparently has a common NT/'95 version (Alpha 3) that
they are holding off releasing until they fix some of the major bugs.

If you find out, tell me.

That depends on what you do in HTML. This is not flippant -- what I mean is
that the specific application of java is important. Let's look at a simple
example -- ESPN's scoreboard (courtesy of J. Payne). While the scores are
updated constantly, Mosaic and Netscape users have to re-load the page to see
updates. Java users see the changes as they occur -- real-time updates.
The same principles are applied to a greater extent in jMUE:

Or how about an interactive stock-market page? The "main" area could be used
for real-time interactive stock trading, while a "ticker-tape" quote board
scrolls across the screen. Several stocks or averages could have continuously
updating graphs showing current values and trending information.
What you can accomplish is limited only by your imagination. The key
differences between java pages and non-java pages are:
* Java pages can have embedded applications (applets)
* Non-java pages are limited to static (snapshot) information

No. The beta version is under development, but is not available from Sun,
and will not be available until next year.
