Seriously, it's just ridiculous. There is no legitimate reason whatsoever to make hard browser whitelist like that in 2013 -- without button like "use anyway" or something. It hard-blocks even the new Opera, while the new Opera uses the same exactly engine as Chrome. And you can't just simply spoof user agent in old-school way, no, it uses client-side detection, so you should make GreaseMonkey script just to run the app. On the other hand it doesn't warn Chrome users with HW-acceleration disabled, and just breaks. It's IE6 story all over again.
