I have a branch somewhere that has a variable spindle speed selection 
incorporated into the motion Component.
The variance range and period are configurable. I wanted it to use a m code or 
g code to set it ..it was roughly patterned after okuma's if someone wants to 
finish the gcode part....

There is no need for a new component, it could be easily done with siggen:

Wire the spindle speed request into the "offset" pin and run the
spindle control from the output, enable and alter the dither amplitude
from a slider in PyVCP (or even enable a fixed amplitude with the mist
checkbox, for example).
