What really amazed me though was both the persistence of this hacker (looks like the project took more than 3 years from first playing around to RE) and the ubiquity of the (I)TRON operatings system that‘s super hard to find anything out about, especially in light of its worldwide use.

I use it with an SD-to-microSD ribbon inside an iFlash adaptor in an iPod. That lets me share SD cards over WiFi to an iPhone.
The main problem would be to figure out how your camera saves the files (it might not save them in a playable format right away - for example it could save most of the data but keep the key frames - necessary every so often - until the end or so, or do more processing on the video file only after recording is finished). Unless you reverse-engineer all that and work out a way to generate a playable stream out of the intermediate file, you’re out of luck.
