I'm guessing the SleepTracker uses actigraphy, which is just body motion. Actigraphy is less accurate for sleep stage measurement than EEG, but it's great for detecting movement and snoring. I'm currently doing a side-by-side comparison of the Zeo and the FitBit, which is similar to the SleepTracker.
I do think the polyphasic sleep people are kind of nuts as I haven't met a single person who's strictly adhered to it for more than a month. Almost everyone I know who's done it admits that they take naps periodically or occasionally "crash" to supplement the sleep regimen.
Also, clicking through to your facebook profile, it appears we went to the same high school. Yes, the bay area is great for filtering by interest. Not a coincidence. :-)
