Paul,

 

That sounds very interesting.   What type of refresh rate/how quickly do you think it could update the pwm of all 204 channel?  The MAX7313 sound like it might work very well for me.  I like how they added more device IDs via that creative scheme (connecting pins to SCL and SDA)  instead of just adding more select lines.

 

Are you or your friend using the MAX7313 to drive LEDs directly?.   I may be driving banks of LEDs per channel, or using high power LEDs such as luxeon 3W and 5W, but I could just use the 7313 to switch a transistor that could handle the current.

 

Also, thank you for your input David.  I will have to try that out on a bread board tonight.
