The easiest is to include it into oFono source.  We do support external
plugins but I can't point you to an example off the top of my head.
There were a couple of external plugins in the past.  See src/plugin.c
and Makefile* to see how to do this.

This can be done by setting the plugin priority appropriately. Plugins
with higher priorities are queried first.

Sure.  Python just gives you an example of what D-Bus properties to set.

No difference in the end.  For an embedded system which has no user
input, the provisioning approach will likely be easier.
