I think the biggest obstacle right now is not the software, but the hardware. The software works, but requires either buying a $300-$500 set of three circuit boards, or finding a specific PCIe capture card and potentially modifying it. If someone made a nicer version of the Domesday Duplicator - single board in a case, $100 to $200 - I think that would make the project a lot more accessible. Even better would be if someone started selling modified VHS players, having replaced their normal electronics with a capture device and a USB3 port. After all, many people don't have a soldering iron or a desktop computer.
