Wouldn't writing a portable library be an idea? The interface
would probably be relatively simple, and code reuse is always good.
My guess is that the routines for Linux (which I can't get to compile
anyway, because of a missing file...) could be reused with little or
no modifications.

Me too -- it's by birthday today ;-) (Just had to mention it...)

I'm sorry that I don't know about UltraSPARCs (but I would give my left hand
for one), but why is this the case?

Running Prime95 on a Windows CE machine -- isn't that a bit optimistic at the
moment? I mean, even my (erm, it's not mine) trusty old P60 has problems now
(earlier I used to get some smaller exponents from George, but now I guess
such small ones are only available for double checking). A Windows CE version
would drain battery and just be overly slow. (I really hope it was meant as
a joke ;-) )

Like consoles? ;-) (OK, they don't run Java.)
But I think this might be interesting, not only for non-ported-to platforms.
I think we just discussed this, but it would be nice (for newcomers) to load
a page (any page -- this applet could be spread on thousands of users' pages)
with a factoring applet on, and get the message `Thank you for contributing
some CPU time to GIMPS. Click here to find out more.'.

>You may be surprised at just how fast a Java implementation could be.
Yes, especially with JIT compilers. (Wasn't Java really made to be quite fast?
I can still remember when I had just received the JDK, and used it for
almost everything... Because it beat VB (4.0) hands down, at least when it
came to speed.)

Multithreading?
Key rule: For a system with only one CPU, multithreading will not make it
faster. But who knows, those monsters may have 256 of them, for all I know.
At least they're expensive enough.

That's the closest thing you get, I agree. We do not need a GUI for Linux
in any way. mprime has already got an excellent (text-mode) menu, and runs
in the background virtually all the time anyway.
