Webkit-derived browsers support the blurring but do not seem to support
removing the filter via :hover so that would need some mouseover script
to compensate which is easy, for Internet Explorer the proprietary CSS
filter extensions would have to be used probably in combination with the
mouseover scripting needed for Webkit, so for the mainstream browsers on
the desktop I'd say give it two hours. The minimum you need to blur on
the client side is scripting, access to image data (likely via <canvas>)
and a way to render in-memory image data (likely via data:image/png,),
below that you would some fallback, like showing a single-color image as
temporary replacement instead of the blurred images. So, quite good.
