The back end engine currently runs under Win16/Windows95/NT.  Most of it
has been ported to the Mac and finishing the port should only take an
evening.  (I had everything running on the Mac. not too long ago but I
need to port/recompile the changes I've made since then.)  I hope to have
a Unix port in not too long.  (Basically, it is a matter of when I get
around to doing it -- it should be quite trivial.)  All files are binary
compatible between platforms.

> I'm also wondering, if there is a manual way to copy files/documents on
this platform, what happens to the links when a document is copied (or
moved) to another location.  Basically I'm asking, are the links relative
or absolute... ie. does the operating system support the maintaining of
links when a document is moved to another location? 

Yes, you can copy files/documents to another location and your links will
remain intact.  Links use a document ID so you would need to register the
move with a document database.  (Or, that could be built into the copy
program.)  You may also trade your links with others who have the same
document.
