The nice folks over at Computer Systems Odessa (they make ConceptDraw) have made available a web service to convert files from the binary .vsd file format to the Visio XML document format, .vdx.
So, if you're stuck with a bunch of native Visio documents but don't have access to Visio 2002 or Visio 2003, you can use this to convert them to the XML format.
I expect this to become a very handy thing to have at hand, thanks and kudos to the ConceptDraw folks!
