--- Comment #1 from Petr Spacek pspacek@redhat.com --- Please just note, that there is a possibility that this feature will be pulled out of Fedora 19 release in case we do not manage to overcome challenges we face with this feature in time.
As Jaroslav stated above, 2013-10-08 is the day when this should be resolved.
