Yes, NM doesn't use the session bus at all.

If you have basic routing needs, you can add routes (or override the
automatically determined ones from DHCP or VPN) in the connection
editor.  Otherwise, you can add a dispatcher script to do the same thing
if you really want to.  Google around for them, the format is the same
in 0.7 though with 0.7 you get both the IPv4 and DHCPv4 configs added to
the scripts environment.

Why is that?  NM needs to merge information from various sources into
your resolv.conf, plus that configuration certainly won't be valid once
the interface is down.  You can add your own custom search domains and
DNS servers for each connection if you like though.  Could you describe
your use-case a bit more here?
