Probably it is doable on top of ZeroMQ too (+ few bits sqlite around the 
restarts) and IMO zmq is relatively closer to dbus compared to AMQP.

But it is possible to rework dbus in any of these ways (inject 
persistence, adopting different messaging core) in the F18 timeframe? 
May be we should look at the proposed feature as unfortunate temporary 
workaround for the problem introduced by accident in the past, which 
should be properly addressed for F19.

As I understand the proposal, the necessary workaround only affects the 
desktop instances and specifically Gnome ones - I am under the 
impression that my servers will continue to be updated by the normal way.

Kind regards,
