Simple and cheap an ubiquitous 'detectors' that can virtually instantly add to a standardized database of sightings is a fantastic idea. It's the value of quantity over quality - refer to the WW2 Germans about that for a refresher. Also, look at how amazing crowd funding can be. The concept of making a simple plug and play, fire and forget gadget available to the general public is fantastic. How many organizations and individuals have collected reams of sighting data and then did exactly what with them - let anyone that wants to come and look? Great if you're writing a book but otherwise - and I hate this term - is building a silo. A mass appeal approach, which I don't think the MADAR folks are quite up to speed with, is the closest thing I can imagine to having a coherent database of 'big data' to mine. Mass samples can be very revealing in surprising ways. Problem is, just what the units themselves are capable of reporting right now is questionable. Garbage in, garbage out.
Oh, to CO - if you want credible investors looking things over maybe put the reports of Bigfoot Portals on a different map.
