The problem with SVG is it's support inside the <canvas> tag.
On FF, you can draw a svg inside a canvas, and retrieve it as a raster image, via toDataURL().
Chrome (and WebKit in general) has a browser-wide bug : when you draw a SVG on a canvas, the canvas is set as 'tainted', and you can't retrieve the raster image.
Since everything in C2 is based on canvas, you need to work with it. That's why my SVG plugin is on hold, I'm waiting for an update on the WebKit side...
