I know exactly how you feel, Andy, about the euphoria. Lee, you have certainly been an inspiration for all of us, especially how you've figured out how to overcome the many technical problems associated with live scans. Interesting about Hao Li's work with Arctec, although it's still a bit too expensive for my budget.
Speaking of problems of of the lazy-susan, I'm planning to use a camera dolly on a circular track that goes around the model, always pointing to the center to capture a (as still as possible) model. I'll let you know how that works.
I'm using 6 Canon SX130s (got refurbished ones for about $120 each on ebay, sometimes they're cheaper). With a lot of overlap, I'm happy with the results of inanimate models.
Sync is a challenge; I've been fairly successful using the CHDK, which most Canon point-and-shoot cameras are able to use as a multiple camera sync hack.
http://chdk.wikia.com/wiki/CHDKUsing USB cables, I can get the 6 shutters to remain open for 1/10 second, and now I'm working on some circuits to fire the studio strobes during that 1/10 second.
BTW, Andy, there are some useful posts in their forum about writing a motion trigger for lighting capture that discusses the issues you raise. Not sure about applicability to DSLRs, however.
It's great to know there are others working on the same challenges! Looking forward to further collaboration.
