True, but I don't think the HomeKit sales are of the volume near the current automotive monthly sales. The issue is going to be greatly expanding the piecemeal type of sales similar to automotive. Expanding additional cotton, polymer textile or expanding into Pharma, leather or wool wouldn't require near the number of batches (independent of batch sizes) and all the associated quality testing and approvals that each batch goes thru to maintain the integrity of the program.
So a drum or multiple drums of a single product batch goes thru the same set of analytical testing and quality approvals as a small jar of product used for marking a single car or a single household kit.
