I saw a similar safety-system at Hanover industrial fair a few months ago. So they are already being sold.

  I'd love to see it! Can you send me some details via email (in my profile)? Thanks!

    Sadly I dont remember the details anymore. I can just remember that the system was by a german company and judging by how it behaved was still in a kind of beta-stadium.
