Here's an example SVG that works.
<?xml version="1.0" encoding="utf-8"?>

I'll try and see if I can get a hold of Illustrator CS 2 to see any differences, as a last resort. I have CS(1), so the difference shouldn't be too big.

I've updated the site to reflect a few things:

Most importantly, the exact settings I've used to generate a readable svg for our importer. http://ghost-hack.com/p5/svgcandy/settings.jpg
Let me know if this helps.

BTW I don't remember seeing "optimize for Adobe SVG Viewer".
I appreciate the help testing
