I'm surprised nobody mentioned Soft errors, except the PP. Alpha particles comes not only from space, but like cellular radiation and everybody fearing the tower while under inverse square law the danger is the phone, alpha particles can come from the chip package.
It's pretty rare, but I have already seen it with recent chips from a manufacturer. The manufacturer acknowledged afterward before the evidence: high exception rate, way higher than what avionics get up in the sky. Material of the package was changed and life went on with usual software bugs..
Hard realtime works great on Linux, but choose your manufacturer carefully. All the following are free and open source.
When it comes to hard RT extension (even in userland), I tend to prefer Xenomai over RTAI. Xenomai has better non-x86 support (ARM is there), nifty so-called skin support for legacy API's (VxWorks, uITRON,..), and very good community.
Talking about distro, ELDK is best what comes to mind. This is industrial grade software, free as in beer and speech, but with commercial support if needed. The toolchain is excellent. What goes into the flash image must be hand-picked because only you know the necessary stuff.
If you are in D/A A/D business, then have a look at Comedi, it is also RT enabled by the comedi-rtdm project.
All these tools/projects are used and backed by industry. I'm a simple user of these tools, and they make my day life happy.
A TV mockumentary "Citizen Cam" was broadcasted on the european channel Arté for the 1st of April couple of years ago.
"Jerome Scemla's short film Citizen Cam tries to address the issue of surveillance from a mass culture perspective. The twenty-minute documentary tells the amusing story of a public television channel in Iceland controlled by the police force. The 24-hour channel shows twenty second footages of surveillance cameras that are placed throughout the city of Rejykvik. The film includes interviews with the channel's opponents and supporters. But when a local priest claims with childish pride that he "is proud of his people" because "no one has tried to commit suicide on air," the viewer begins to wonder if they are watching a documentary, a mockumentary, or an Icelandic version of Surviver. A policeman tells an anecdote about boys who staged a bloody twenty-second gang fight in front of one camera. Citizens throughout the city began to call in the station, claiming that they were eye-witnesses. When the police arrived at the scene, the boys were jovial and triumphant over their successful charade. The film makes the point that in an age of almost ubiquitous surveillance and sensational reality shows, what's true and what's not is more perplexing and enigmatic than ever. "
I've almost been had, but realized it was a joke when at a moment in the film, grand'mas were watching the "Humani TV" to know how to dress, depending on outside people outfit.

Z: "What do you call them?"
B: "Well, they are tasty, right? Let's call them tasticles."
C: "Eww. Oh my no."
L: "We can't call them that..."
B: "Why not?"
L: "It sounds too much like those frozen Rocky Mountain oysters on a stick. You know, testsicles."
With the increased bandwidth generated by the git repositories, better than ftp mirroring, distributed sharing would come handy, releaving feed pipe and average load too.
However, in this post from hpa, it looks like the tools are not ready.

Long awaited significant improvement on symbols visibility.
Saves RAM, saves disk, and as a consequence, allows to save link and load time.

/. caught again on buzz words with a shallow article.
Anyway, what we need is not an autovec compiler, but instead a library with most CPU hungry algorithms well implemented with SIMD extensions.
What about an open library, cross-platform, multimedia oriented, along the line of SUN's mediaLib ? Would SUN allow the re-use of their API ?
I'm looking for such a library, with GPL/LGPL compatible license. The API has to be in C, to maximise audience. For many projects, C++ is not an option.
Primary use will be DSP work in GNU Radio project, but multimedia extensions could prove useful anywhere in GUI's to audio/video app, etc.
I would take any pointers to such an already existing API/project, or be ready to start a new one, if other people interested in.

How similar is this to FON ?
Frozen-bubble should be available for mipsel: http://packages.debian.org/etch/mipsel/frozen-bubble/download
Done already, and it proved useful. Have a look at crashme. That program is also part of the Linux Test Project.
During the video, an amateur theater company did also get imaginative about the use for CCTVs.

Oh, and it's a very bad idea to put swap in a Flash device, unless you want to wear out the sectors pretty quickly and render the chip useless.

Too bad the name exists already for the Dream DRM receiver http://drm.sourceforge.net/, which is, for one, a dream come true.

Other solutions? Check out also CWirc (morse over IRC, with paddle and sounder). There's even bots and qsb/qrm generators.
