What do you think of my idea? - Screenshot as SVG SAAS

Hi guys, I've built a couple of screenshot saas's in the past for personal use more than anything, but came to a realisation the other day that there are no screenshot services that return SVGs.

You can read about pros and cons all over the web, but the thing that drew me to the idea is that they are infinitely scalable, because they're vector based rather than rasterized.

Before I throw up a landing page etc I just wanted to get your guys thoughts on whether you would find it useful.

Cheers!
