Yes, MindfulCoyote is right, a "gold" or whatnot, subscription to ESF includes the paid support, online "cloud" backups, and a book.
Seems I'm not the only one curious about the release of the bundle of paper for v 2.0.
Alas, not everyone has the budget to "go commercial". Some think that "commercial", is really the future direction of pfSense & ESF.
Some prefer to run their own "cloud", say, for example, using FreeNAS or NAS4Free.
