I wondered how long that would take as shooting video or not is a firmware decision, not a hardware limitation.
Though as it only works tethered, not the most elegant of setups.
What I'm more interested in in a 5DII hack to allow manual control.
There have been hacks for Canon P+S for many years to allow one to shoot RAW or have more controls/featuresHacking your IxusCHDK
What would be really good is to hack the D3 (or a canon) to shoot stills at 1k at 25FPS, the nikon does 13FPS on jpg small which is 2k quality - same data rate - full manual control shutter and ISO
then would have raw and no silly compression issues
