Hi all,

I'm working on tracking multiple unique objects within a space about 15m square. Line of sight issues make video or infrared tracking problematic so I'm looking into triangulating cheap ultrasound devices. I'm curious if anyone here has worked with Max and CSAIL's Cricket devices (http://cricket.csail.mit.edu/), and if so was your experience was like? Or if not Cricket has anybody had success with ultrasound sensor networks in general?

Cheers all,

Jason
