Nate:

Couldnt agree more. Fact is, bevels are hard, Ill try to make it so some work, some dont, basically we'll just have ot
live with whatever we ifnd the limitations are...unless we all want to buy 5th axis machines.. :)

On second thought, it may be possible on that 4th axis after all, but it will require the cutting tool and the gear axis to be skew to each other.  (I'm not sure what the right term for that is.)

Just for fun, a 45 degree chevron bevel gear section - these really want to be 3-D printed, if anything.

I must admit, bevels is one reason I like 3d printers.. :)
