I'm very interested in this technology (and somewhat skeptical about it). The website is very opaque on how it actually works, and "signature correlation" doesn't appear to be a well-known term (http://scholar.google.ru/scholar?q=signature+correlation+lid...). It also appears to not be based on time-of-flight measurement.

It's also not clear for me how are they going to make a production run within 2 months (funding ends with Feb, shipping in May), much less so for a project which includes an ASIC.
