This idea came to me when Ch3vr0n posted the message below, ... My idea is for people not buying many disks often, during the year. If they ever figure out a way to do it, plus be able to add that new smaller file-piece to it locally ... They may be able to create, and offer, another type of subscription method...to update ones own master database download, on a disk-by-disk title method, instead of yearly, or LTL type license. In other words...a customer can put the title names into a list, then, just the decryption files unique to the customers needs will be downloaded, and added to their own personal master database..! In the long-run...it could also be more profitable to receive $1 or so, for each title needed, rather than a flat yearly subscription amount....but less expensive for the customer, just paying for what they personally need. With maybe bulk purchases discounts for the power-users with many titles per month or year.
