We have a large testing infrastructure consisting of shielded boxes, 
attenuators, etc. It is all exercised using tcl scripts and none of it 
is open today. Who knows what tomorrow will bring. The brcm80211 
open-source drivers are tested limited but nightly using it.

I am considering coming up with a new test framework for the brcm80211 
drivers using python scripting, which is why I started py80211 
experiment (available on github), but your mentioning of autotest makes 
me want to revisit that.
