I only run AIM under Windows 2000, and my servlet mod works fine under that
OS.  I wrote it so that it would be compatible with Linux also, but I
haven't tested that in quite a while and the last I heard from Greg was that
it was hanging sporadically under Linux.  I think the problem might be the
difference in the way the two OS's multitask, since it is using a separate
java thread to monitor Maple processes so if they go awry they can be killed
by the original thread.  I have not tested it under Windows 95/98, though I
assume it would work under XP if it works for 2000.

I was going to try to fix the problem it has under Linux, but even under
Windows there are still situations where a wayward Maple process can crash
the entire server.  So I abandoned that work and decided to move towards the
distributed TCP servlet design.

Still my current servlet mod does work as claimed under Windows 2000, adds
some nice new features, and is somewhat more robust than the current
distribution.  So if you want to distribute it with the Windows version of
AIM, that would be fine.  The only problem I could foresee would be if it
doesn't work under Win 95/98 for some reason.

Unfortunately not in time for this release.  My student was working on it,
but I have not been able to contact him in the past few weeks. He is
thinking of using this as part of his Masters Thesis project in software
engineering, and classes just started today, so I would say that you should
consider that servlet project to be a long term project.
