Hi Bill,
Somebody eventually responded to my original
post on the networkmanager list and said this
in response to my first question:
"Yeah, reconnect of a failed connection (as opposed to a
user-disconnected one) is definitely on the list. I was planning on
doing some of the work for that in the 'inhibit' branch in git, so you
can track that there. It won't be mobile-broadband-specific at first,
but the changes there will help out the mobile broadband stuff too."
Somebody asked a similar question about VPN
and the response was basically the same.
Nobody answered the other questions
(except you).

I do know about /proc/net/dev that has per session statistics,
but I was wondering if networkmanager had a way to accumulate
over multiple sessions. I think the answer is no.
