IMO the idea is neat but the implementation concept is flawed. Template and bearing guided routers use solidly fixed guides, including the edge of the workpiece. The way this is done with stick on tape looks a little imprecise and does the machine produce the tape or must you buy a special printer?
For pro and semi-pro use I would think some kind of reference frame clamped to the work would be better, either with conventional CNC router guides or even reflective targets for a laser. For larger work the frame could be re-positioned using alignment marks that could be sanded off later. I would also prefer more than two traction rollers to make it more controllable with larger bits. They do have some interesting partners but IMO this will be a novelty for well-heeled hobbyists and later entries into the market will address the shortcomings I noted above.
