That's a cool idea!
I've been building a RaspberryPi to use for site surveys.
The plan is to have one at each of our tech-depots and have a local tech take it to a site (grocery store)
where we're having a problem, and have them leave it in various spots for 30 minutes to get a clearer
impression of actual conditions.
We've got kismet on the RaspberryPi and will have VisualRF do surveys. We can compare the two devices'
opinions of conditions.
