Pointers to programtatic detection of AppArmour and a couple salient 
details about firewall (enabled, perhaps number of rules) from any 
quarter would be welcome.

Plot thickening, seems that autotest knows about some version of 
netperf2 already...  i'll be trying to see if there is some benefit to 
autotest to netperf2's top of trunk having the keyval output format, and 
if autotest groks paired systems to more easily do over a network testing.
