Multithreaded h.264 decoding is what I'm missing. Still only slice-based multithreading support, which doesn't work with 95% the content out there, which means you can't get real time decoding of full hd content on A64 X2 (core2 cpus are probably fast enough even with one core, at least the faster ones). ffmpeg-mt branch fixes this, I wonder when this will be merged (still seems to be a bit buggy).

If you pair atom with the poulsbo chipset, it certainly won't require a fan (I'm not quite sure in which environments it could run even without a heatsink). Even paired with a 945gse instead (but not the 945gc) it doesn't really require a fan neither. Not sure about nvidia's ion platform...

For the 3-min charge of this thing here though I doubt just installing a new breaker would do. I'm not sure about the US, but I don't think you can actually get that much power delivered to your home with low voltage. To charge such a battery in 3 minutes would require _over 1 MW_ ! Would require something like 3x1600A at 230V, and twice that for 110V. Needless to say, that would require some serious cabling... Of course for industrial use you can get a 20kV connection which should easily do... If you'd be content with 1 hour charge of this battery though, you'd only require about 3x80A at 230V, which electric power companies indeed provide (though most one-family houses here are limited to less).
