It's going to be an interesting week. The conversation at Print Ceo is starting for real.
The vulnerability of the Espresso is that, as I understand it, it is PDF based. The network agreements that Jason Epstein has put together with publishers is a very defensible value. But the amount of content in PDF is dwarfed many times over by the content in XML.
Wikipedia is in XML. PediaPress in Germany has been selling Wikipedia in Print for many years. Obviously they have a done a deal with wikipedia to share some of the value. From what I can see, the books ordered by Pedia Press customers is for a very narrow market. And the production model is print and distribute. I believe that Oce is the output device.
But, the Xerox + Espresso turns that paradigm on it's head. Any book, any where, any time has gone from a vision to one more way that digital print can change the world.
At any rate, here's my two cents:
Partner with the best XML to digital print stream people you can find. Get the engineers to add some binding to the MFP. If it were me, I would do it faster, rather than slower.
