M1 Caliber - Miter Saw Fence Measurement Roller

Anybody take a look at this one yet? 
 





It's a neat idea, but I don't know that I'd be happy with it. It seems like I always end up with measurements that are a pencil width left or right of the measurement on the tape, and it'd be hard to noodle with little tweaks like that.

I think i would rather see a some sort of laser tracking measurement than a mechanical encoder. how would a 45 degree miter work on something like this?

Really cool,
I can see some limitations, but for the most part it should work well, especially for job site framing and flooring jobs. As for cutting miters you would always have to make sure your leading edge is against the fence.
