Here's the status of the various ports:

Mac:
Josh Adams <jadams@hyperimage.com> mostly finished this, based on a beta
of 2.0, but never released it for some reason.  If I can borrow a Mac OS X
machine for a day or two, porting it should be easy now.

Java:
There are a bunch of Java ports around.  I've never found one that works
well.  I started porting 2.0 a few years ago, and never finished.  It's
possible I'll start again.

XFree86 for OS/2:
Darwin O'Connor <doconno@cc.UManitoba.CA> ported 2.0, and you can get it from
http://www.reamined.on.ca/doconnor/xprogs.html.

Linux SVGA:
I got this mostly working on a beta of 2.0, but it had a couple problems
(mouse support wasn't very good, no menus or windows), and is now hopelessly
outdated.  It does have an XPM and XBM reader.  If anyone wants to finish
this (write the missing parts and the new parts), let me know, and I can find
the old code.
