[CoLoCo] wireless airscaping

[David L. Willson]

I want to get a picture of how busy the various wireless channels around
me are.  I thought swscanner might do it, but I can't it to run right.
I see the networks clicking past, but when I click scan, it segfaults.
I don't need to crack or pen-test or anything, I just want
signal-strength and channel for all running wireless nets.  Is there
maybe an option to nm-applet to get it to show the channels?  Or
something that makes pretty little charts, better yet?
