Craftsman Compu Curve
I just saw an ad for the Craftsman Compu Curve and was impressed. Basically it is a computer / cutting saw that can read data on shapes and designs and then cut it for you! I could have a lot of fun with something like this if I had my own home. If you have used it please place a review here.

That would be handy. I would have liked to of used this when I was a cub scout.
Bit durability should not be an issue as industrial bits have been perfected for many years now. As long as you do not try to drive it too deep to fast. I would think like a drafting printer one could have multiple tips and it would grab then as required as long as you put the right on in the right spot. Many commercial machines do this.
If not not a big deal you make one cut change tip then do the next round till done.
