I agree, though apply same to Suite Owners:
That makes a great deal of sense to me!
~Give library owners one serial that is good on all products and updates unless/until they cancel.
~Suites might be more of a pain, but owning the SuperSuite and some subsequent upgrades, I would LOVE to have one serial!
Perhaps the "One Serial To Rule Them All" could be linked to each customer's WA Account, which already contains the data on what products and versions each of us are authorized to use, whether we go through a product, a Suite, or the library. That being said, I have no clue how you have the serials set-up on your back-end, and I may have just inadvertently given a WA employee nightmares, but that sounds logical to me/ ;-)
