Make Data Driven Pages publishable as a ArcGIS Server service.
It could be a sub service to map service (kindof like feature services).
Advantages- DDP services could be used easily by non-programers in applications like arcgis.com or Flex Viewer.
Formated and customized maps would be available to much wider audiance.
There are no good (non-programmer accessible) printing widgets or applications in the whole world of web gis. DDP service would bypass the need for tricky printing applications.
Please feel free to enhance this idea if you have good things to add.
