title: Convert .ai to SVG on upload
body: <p>I want users to be able to upload <code>.ai</code> files but to use them in the t-shirt editor I'm working on, they'll need to be <code>&lt;svg&gt;</code> elements. I know Inkscape offers this ability with <code>--export-plain-svg</code> but I'm having problems getting Inkscape to work with Heroku.</p>
  
  <p>Are there other tools out there for converting <code>.ai</code> to SVG on upload?</p>
  
  <p>To be incredibly specific, we're setting this t-shirt designer up in Rails, so it'd be extra cool if this tool was Ruby or JavaScript based.</p>
