Ok, if everything is battery-powered, you're good. However, as soon as mains power is involved anywhere, galvanic isolation is a must just in case there's some sort of short circuit. I was lucky (or prudent, don't know which) enough so far to avoid any encounters with mains voltage, however, as the firmware guy, I don't do quite as much poking around the internals of, say, power supplies as the hardware guys do.
The other one takes those and handles the SPI for writing to a memory card.
Hm, an interesting dual-processor setup. Does it have any advantages power-wise compared to, say, using one of Atmels ARM chips? That's what I am working with right now. If you're planning to have the device running on batteries for a week, you're probably looking at an ever more limited power budget than I am.
I'd be *very* interested in hearing more about your design: anything online?
Since this is part of my job, I'm afraid I can't spill any corporate secrets.

And I guess you didn't read my post.
It doesn't matter when google decides to refresh it's cache. You can still get an invalid entry, an entry they haven't cached, or an entry that is currently being refreshed.
Any DNS server can choose how frequently to refresh it's cache, whether it updates or purges during a refresh, and whether or not to return the stale result (be it stale according to the official TTL or stale according to your own refresh frequency) while refreshing.
Updating your cache 1 hour before it needs to be updated is not magic. They just use a higher standard for the expiration date, and pay a price for it.
Sorry, you can't yell fire in a crowded theater because it could potentially harm a large number of people. I think it is fair to say that a channel portraying itself as a News agency has to be held to a higher standard than a channel such as Comedy Central which clearly states that their news is fake. In many ways its false advertising but those laws don't apply to the press when really they should. The truth is not subjective and disseminating false information I believe does harm a population especially when you can disseminate it to millions.
While I agree that you should never trust 100% any one entity I also understand that the vast majority of the country doesn't want to try that hard to get news so they end up watching MSNBC if they are Democrat or Fox if they are Republican. After having watched both I can saw however that Fox actively works to distort reality such as using footage of older rallies with larger crowds and the outright lying about Jon Stewart's stance towards global warming. Some of their actions are truly atrocious and damaging to the political climate. Debate about issues is healthy but Fox isn't promoting discussion, they are actively promoting an agenda. If they didn't call themselves a news network no one would have a problem with this.
Shaw cable, in BC, Canada now sells "High speed" with"Powerboost" which means your connections are throttled after the first few seconds of connecting. It seems a good way to do it; people just surfing have a good experience, but torrenters still have fairly high (but not as high) speed access. Sadly, they market it as medium speed with boosting, not throttled high speed which it is.
The same can be said of The Times in the UK. One of Britain's longest running papers and holder of all sorts of semi-official roles (newspaper of record, for example) it was bought by Murdoch in the '80s. Many of it's best editors were replaced or quit (highly respected Robert Fisk, for example, resigned because of political censorship), and it's focus shifted onto more popular subjects (celebrities, sport, etc).
It has also always backed Murdoch's candidate-of-choice in elections; during his support for New Labour it made many attacks on the Tories, and since Murdoch started backing the Tories again their focus has swung back the other way (although they're more natural Tory supporters anyway, so at least we're back where we started).
And let's not even get started on The Sun...
