IPEX Daily has been printed ok from PDF. Creo's presentation of Networked Graphic Production seems to complement Adobe's Network Publishing, though obviously with a print bias.
Print City is getting better at explaining workflow and the links to work on the Job Definition Format. From discussion after their presentation it appeared that practical links may follow IPEX across the way things have so far been presented, for example workflow involving MAN Roland and Creo.
There was frank admission that explanation of workflow issues had been poor at Print City's first DRUPA. This may have influenced Adobe's decision not to continue as a member. There is certainly energy going into explanation at IPEX so maybe PDF will be more fully explained at the next DRUPA.
