7! ;-)

In the beginning I wasn't sure how NMs "having a network connection" 
concept was, how explicit it was and how useful it was. I didn't know 
what to google for - and you know how most google hits for NM looks like ...

"state" could mean so many things. I think I thought it was referring to 
the daemon itself, not to how successful it had been managing the 
network. "The overall state of the NetworkManager daemon" is IMHO not 
exact. Something like "The overall (connectivity) state of the 
NetworkManager connections" would have helped me more.

The documentation in spec-08.html looks nice, but the deep nesting and 
lots of whitespace makes it easy to get lost. (Minor comment: It would 
help a bit if method names GetDevices were marked up as code.)

Try to search through the page for "state" - there are lots of hits, but 
they are referring to different kind of states, and it isn't obvious 
what the context is.

Once I know what to look for and code against there were no problem. 
Especially with the help of d-feet. (D-bus hint: Accept that you _do_ 
have to repeat yourself all the time ...)
