Right, but the NM startup is the part that's going to kill you here...

Obviously this isn't something that's easy to do, especially with the
richness of configuration and the number of interfaces.  It's also much
harder to do for anything except wired, and it's probably pretty hard to
do for wired 802.1x-authenticated connections.

Yes, but probably not before 0.8 I think.  I believe it would require
quite a bit of coding and architecting to ensure that it's not an
un-manageable hack.
