This looks like it might be a pretty good idea. It seems that it could make the lens easier to store mounted on the camera and would certainly be quicker to get into use than storing the lens with the lenshood reversed. However, $49 (USD) is a pretty high price to pay for something I don't know if I will like or use. The price is the same on eBay and is quite a bit more ($68.20) on Amazon.com...
