That was a pretty good quicky Genome came up with for modeling the supply current of an opamp - for the problem a hand. In case you missed it, here it is:

Works for modeling the current once the diode turns on but there's bad crossover distortion.
Take the circuit from the "strange amp - MVC-324X.JPG - T600amp.jpg" thread. Ok, don't take it. It's supposed to be an amp, not a switch. So using the diodes to separate source and sink currents works, but you get that distortion.
How can we model the supply current without the diode distortion?
