well cool - I'm glad you actually shared it. It's also a good time to
actually stick our heads together and come up with a decent plan going
forward. One of the things we will want to avoid is to make
non-upstreamable code for the parts where it makes sense, for
instance, so implementation details do matter.

thanks for writing back quickly - I really appreciate it.

We also need to figure out a way to get your dbus patch accepted
upstream, and perhaps this is something I can further help with.
