As far as I can tell, I'm implementing the Client.Handler interface.
HandlerChannelFilter property is: dbus.Array([
CHANNEL + '.ChannelType' : CHANNEL_TYPE_DBUS_TUBE,
CHANNEL + '.TargetHandleType':
CHANNEL + '.Type.DBusTube.ServiceName' : SERVICE,
Capabilities property is dbus.Array([SERVICE], signature='as')
where SERVICE is 'au.com.baum.example'
I don't think Mission Control is picking this up, because Empathy gives the
message "An invitation was offered for service au.com.baum.example, but you
don't have the needed application to handle it", though that could be
something else (like me not returning True where I should or something). Also,
HandleChannels is never called.
The tube itself works - calls and signals go from one side to the other.
(That's via the NewChannels signal to grab the tube; taking that out makes it
not work at all.)

That's still the case.
