I think (relying on random docs here, I've never used it, because I
assumed there is a good reason for nobody using it ;-) peer-to-peer
dbus connection just sets the connection up using the local socket
path directly.

The way you'd *want* dbus to operate would be direct writing to a
peer-to-peer socket at all times, and only going for the daemon when
that socket dies (to get a new name mapping & socket).

There seems to be widespread confusion about dbus details, including
an assumption that it already works this way ;-).
