I don't see it happening any time soon. It's something I really want. It would help me a lot. What I have now is just clumsy, so as much as I like using the pis, I only use them for major builds these days. And I'm not really a coder now. I used to program a lot. These days, I've been away from programming so long that anything I do takes me an inordinate amount of time. So I'd happily work with someone on this project, my I'm not the one to make it all happen right now on my own.
Another thing I'm thinking that I'd love to do eventually is set a few of them to run permanently in my studio. I used to do that with old web cams. That way, I never had to think about it. If I happened to create something that I really liked when playing and experimenting (as opposed to a planned installation somewhere) and wanted to save the time lapse, all of the data was there. And, it doubled as a security camera. Of course, in this case, I'd have spinning disks hanging off of them so I wouldn't run into the wear issue of SD cards.
