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.

Java:
Greg Seidman <anthro@cs.umd.edu> and I were working on this, but it's been
stalled for a while.  We'll finish it at some point.

XFree86 for OS/2:
Darwin O'Connor <doconno@cc.UManitoba.CA> ported it, and you can get it from
http://home.cc.umanitoba.ca/~doconno/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outdated.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.  So, if anyone wants to
finish this (write the missing parts and the new parts), let me know.
