I would rather not have the bus tied to the .service file and instead
leave that as an implementation detail for the daemon (perhaps with some
standard behind it).  The reason I say this is on OLPC we might want to
make our own daemon which forks and loads python files to avoid the
overhead of loading another instance of python.

The daemon itself should cache service files the way D-Bus does now.
