Again, all this work has been done to support other modem driving
solutions (like mobile-manager). There were two missing pieces: It
wasn't possible to use other languages than C before, which is solved
by writing code to NetworkManager to talk to modems over dbus. Another
thing that was missing was the dbus API. Now that is defined as well
(but is open for changes). There are other (from mobile-manager)
interested parties and everyone has their own API. NM shouldn't try to
implement all of them, so we needed to define something that everyone
can target. ModemManager that I just announced is just one
implementer. As you say, it takes time to write a good one, and using
existing programs (which need to adapt the API changes, or just
provide another set of API to be integrated with NM) we have a
complete solution today.

The way to collaborate (to integrate with NM) is to try to implement
the API I've defined, and give me feedback on what should change
