Whirlwind, the new SawStop?

Alot of great discussion in the comments over at the Wood Whisperer about a possible move to require Saw-Stop like technology in tablesaws.  He also points out a new competitor called Whirlwind that takes a different approach, using proximity sensors rather than conductivity.  Seems like a great idea, and I can’t wait to see if this gets picked up by some of the manufacturers.
