Interoperability is an important part of being 'as good as possible'.  It's
not like we don't want import/export for Visio files just because Microsoft
makes money off Visio.  Having more import/export options improves our
program, not theirs.  The real question is whether anybody cares enough
about the Kivio files to make import/export plugins.  I certainly don't.

That sounds interesting!  Exporting PDF would be wonderful, since neither
Macs nor PCs understand PS by default.  Do you think you're learning enough
PDF to be able to do that?

How are you considering importing PDF?  As something similar to images, or
decomposed into native Dia lines, text etc?

Way other story, and way old.  Though it should be possible with XSLT now,
for Visio2002 files.  The spec is out there.
