Well, Inkscape doesn't convert the blurs to PDF, but it looks like I can export it as a bitmap (actually PNG) and it turns out pretty decent.
Here's a thought. For those who want to "play" with their models, would it be worth a few extra dollars to purchase the Inkscape version? Another question is if enough of our fellow modelers would be willing to download Inkscape to make it worthwhile only releasing the model in SVG format! The biggest concern then, is that they can modify it and do all kinds of things with it, if they're not honest... But then, you can kind of do that anyway.
