QR code for this URL

Just a few hours ago Google announced the latest feature of their chart API: QR Codes. I always thought that it might be cool to have some QR image of the current URL on my website. So, if someone happens to read one of my articles over at some internet café or at a friend's machine, a QR code might be handy for "bookmarking".

Writing a QR encoder with PHP didn't look like much fun though. And then there is the processing overhead, which can be addressed with caching, but that only means more work. There is also that random string DoS attack vector. Far too much hassle, really. But if Google takes care of all that, it's a piece of cake.
