Hi Mario,
While I haven't added up the total "gigabytage" of everything, it comes to well over the capacity of a DVD, or a dozen of them.
That said, I may be able to provide a service using portable hard drives that maybe accomplish what you ask. I would have to think out the details, but perhaps one could just plug in a USB external drive and point the Scenery Library to it.
Deserves some thought . . .
