Help with PWM for controlling servos and speed con

Yes, the new Mega board is really a exciting board. And very glad to hear that you also finish a servo timer library for it.
Maybe later I will get one mega board, but currently I still want to use a Atmega168 Arduino board with 74HC595 to control servos for Synchronized, or "Group" moves just like the SSC-32.
I tried your ServoTimer2 library, but I feel the servos are not Synchronized, are they?
