Very cool! What saddens me is that there is already an embedded computer on the camera! There is just not a good way to program it.
While there are some great efforts, like Magic Lantern, to reverse engineer and improve the firmware, I wish the producers just made the source part of their product. (I don't believe their trade secrets are that valuable to be honest. Not more valuable than letting people builds apps for your camera, at least)
The amazing CHDK: http://chdk.wikia.com/wiki/CHDK_in_Brief for those who aren't aware of it. If I could ensure a new camera was supported, that alone would be enough to make me buy it over any competing models.
There were briefly some Sony cameras that had hackable built in OS. An open firmware or at least apps (Instagram in camera) would be great. Too late now perhaps as the compact camera market is shrinking and DSLRs are premium products?
Here is my rant, as an experimental (panorama, gigapixel) photographer: Canon, Nikon, and the rest of them will go to their graves keeping their firmware closed and un-scriptable. It is a tragedy. Mobile phones and the Gopro are eating their lunch. The fact that there is even a (niche) market for things like the Eye-fi (wifi sd card) goes to show how utterly clueless and behind the times these dinosaur camera companies really are.
Yeah. A great example of how people go wrong when makers focus on the product they're building rather than the people they're building it for.
As a programmer, my natural inclination is to sit in my fortress of arrogance and build the thing that I "know" they need. But learning how to do user testing, user interviews, and customer development has persuaded me that the important moment isn't when the product ships, it's when somebody actually uses it.
I almost never use my non-phone camera anymore because the point for me isn't taking a picture, it's doing something with it. Which camera companies would know if they treated anthropologists with the same respect as CCD scientists.
Nikon and Canon's target market, photographers, want to spend their time taking photos, not writing code for their camera.
Besides, most of the "possibilities" listed in the article are already available on a lot of cameras (like the intervalometer), better done in post processing (like previewing on ipad), or easily done using a $20 wireless remote control.
Don't get me wrong, it's cool that he's hacking on his camera, but I don't see Nikon and Canon ever promoting it or going out of their way to make it easier.
Some Canon cameras are scriptable natively ( http://chdk.wikia.com/wiki/Canon_Basic ) and also using the CHDK extension. I understand the vendor's position on this, the market for scriptable cameras is tiny, you can easily destroy your camera with the wrong script and as any programmable device, your scriptable camera could catch a virus (http://www.youtube.com/watch?v=t6ZJ4cmc2o8)
As a hobbyist photographer this definitely sounds interesting in terms of allowing more control over the camera (especially automated uses, build your own timelapse, get past the 30s long exposure instead of having to buy a $150 canon timer remote, et cetera). But doing anything with image manipulation and transfer (maybe there's a reason Eye-fi hasn't moved into the DSLR space -- no CF version, only Class 6 speeds) seems like a daunting task for the pi..
For those more familiar with the Raspberry Pi, does it actually have enough performance to move big RAW files around? A 5D3 will output ~30MB RAWs and in a shoot you may end up with 500+ of them. Having a Pi transfer/move/adjust them sounds like a slog.
The Pi does about 10MB/s over the network, I believe.
As for image manipulation, sadly, the Pi is fairly fast by embedded standards, but running general-purpose software on a full-blown OS takes a lot away.
For comparison, the original Xbox used an x86 of the same clock speed.
This could be really great if they release an API to interact with the camera hardware. The article linked above takes a negative view, citing old Android versions and so on, but I think this is really a step in the right direction.
FYI you need a powered USB hub to attach that wifi dongle.
I also got one of those small Realtek RTL8188SU wifi dongles and found that it worked very poorly. I don't know if it was the particular vendor I got mine from or the drivers or that particular chipset, but the interface would just stop working if you tried to do anything data intensive or prolonged on it. SSH and VNC were unusable.
I've had good success with the RTL8188SU. Direct onto the Raspberry Pi, no hub needed. Worked away through it, ssh'd in, transferring images, etc for several hours, didn't have to touch it once. It does get a tad warm, though, but not hot enough to worry about.

I steam 720p video for hours on end over a IOGear GWU625 (Realtek RTL8191S) with no problems.
(Requires powered hub AFAIK, I don't think I tried it without though).
