So I haven't really been following this conversation much but by amazing
coincidence I not long ago happened to cobble together something that has
an API very similar to what JP is proposing, it's worked quite well for me
and I can thoroughly recommend the approach.

So if anyone's interested in a proof of concept I have one. Although it is
implemented using gconf for reasons of circumstance so not an actual
implementation proposal. And the code split between two repo' is a little
unfortunate, but hey the (mostly) same API works with c++ too.
