The question was just emailed to us concerning ArcGIS installation and being green; selecting choices for "Download" and/or selecting which install DVD's you want delivered to you by snail mail. I recently attempted several downloads from Autodesk with no success on installations of the software. All downloads exceeded 2GB and eventhough we're on fiber-optics connections it failed on every attempt.
I would like to suggest creating a new option for delivery on a single thumb-drive containing all ArcGIS installs, including Workstation and Data & Maps.
