I've been looking at hardware options. My initial take is to use UDOO Dual board. A few items that I like about it:

- It comes with built in analog audio

- It has built-in WiFi

- It has a CSI Camera connection

These things will make my work a LOT easier. On the software side, there's a program called Airfinder that I'm looking into. I've got to get the UDOO board first, but I'm hopeful that I'll be able to leverage some of these ready solutions to get a quick start to the project.
