Not to go off topic here but I am very surprised you've never had a RA pull a piece of wood into it. I've built cabinets and grandfather clocks for over 25 years now as a hobby and have on a number of occasions had closer misses with a RA than a tablesaw. You do not need to explain the difference to me as I am fully aware of what purpose each one serves.
The point I was trying to make was purely that this same technology would be great on a radial arm saw as I am sure it hurts just as damned much if you were to cut your finger off with a radial arm saw as it would if you simply ran it through a table saw. No?
