To the post, I'm sure I'm not alone in saying that I read it salivating all the while to get to the good bit where the slide show updates without interruption as new photos are uploaded. No dice!

So we're playing a slide show on an Apple TV that can't be updated without stopping and starting the reel? The browser plug-in at Piclens.com, or even Flickr's built-in slide show viewer can accomplish the same thing on any sort of big screen hooked up to any laptop or desktop. I haven't tested whether either will update in real-time (without stopping and starting the reel) as photos are uploaded, because it doesn't need to do that to be equivalent to the above, more involved solution.
