Phew!  

Yes, just to be clear, our api would only call their DBus interface, we would 
not use their C api and all the G stuff that would make us depend on directly.  
No hard compile or runtime dependencies at all, in fact.

Which kind-of makes the whole GConf usage moot?

In theory, no concern to us, but we do need to consider what happens if a user 
refuses to install the Master Provider due to GConf, or Geoclue at all due to 
Glib/GObject.  A nice default is always good.  No Master Provider, fall back 
to a simple guess on what Provider will work best.  No Geoclue, try another 
bankend, or fall back to a simple hostip implementation, or just return their 
preset home location.
