A WiFi card set to "monitor mode" comes to mind... 

A friend and I are experimenting with using a Raspberry Pi with a WiFi dongle attached, sniffing for MAC addresses. AFAIK, the user would not need to hook up to a specific network. So you end up having a solution that doesn't require much user intervention for it to work. Uses less battery life than bluetooth, and likely the user's WiFi is probably already switched on (if they have a phone with that ability). 

Something to think about... If you're interested in something like that, send me an email. Maybe we could work on this together.

Thank you,

Good observation regarding Bluetooth.  I was looking for a solution that did not require a cell phone (just a Bluetooth fob).  Any another indoor tracking technology come to mind?

Thanks,
