If anyone could have built it, why didn't anyone build it until now?

You have projects like http://beagleboard.org/ (beagle xm $150 and $89 beagle bone), and http://leaflabs.com/devices/ ($45 maple), which are all ARM based devices, that have been around for a while. I just don't understand how these guys got it so cheap, which is why it seems like they just optimized the bom to get it to where it is. I'll hand it to them though, that is an impressive feat.

"just optimized the bom" is really easy to say and hard to do. If it was so easy to cut down the bill of materials of what was previously $150+ (Beagle) to $35 (Raspberry), wouldn't TI have done so with the Beagle?

Also, it's like saying that DarkShikari et al. "just optimized the code" to make x264 the best easily-available encoder of H.264 on the planet.

Finally, the Raspberry Pi is tremendously more powerful than the Maple.

Part of being so cheap might be that the main SoC is subsidized by Broadcom. I have no problem with that, TI is doing the same for the Pandaboard ( http://www.pandaboard.org )

They have said the SOC isn't being subsidized.

I'm really disappointed there wasn't more information on what he was running, this is something I'd love to set up on my own, with or without the Rasperry Pi.

It was on HN last year: http://news.ycombinator.com/item?id=2431318 This is the related code: https://github.com/albertz/shairport/

Not quite. From Shairport's README.md: "ShairPort does not support AirPlay v2 (video and photo streaming)."

snos has the correct link above, from the beginning of the video, it looks like he's running airplay-nmt: http://code.google.com/p/airplay-nmt/

The big thing going for them price-wise is that due to them being a charity, Broadcom is selling them the SoC at prices you would normally only get when buying millions of them, rather than the thousands that they will actually end up buying. Plus I think a lot of the engineers etc donated their time, again because it is an educational charity, thus their R&D was probably very cheap. Thus we end up getting a device t…

See I didn't know this. Now it makes sense why they were able to get it so cheap. Getting a deal like that w/ Broadcom is pretty difficult to do imagine.

I stand corrected
