How hard would it be to modify the arudino board to control 32 servos independantly?  This company is doind it with the same chip used in the Arduino board.

I've seen this servo controller before. It's available individually for pretty cheap:

Regarding your question: dunno how to do this with the arduino. But the firmware for this thing is open source, so you can have a look at how they did it.  :)

i think if you try to build the same in arduino you might end up spending more money:)

just buy theirs if you are in the US, the price is honest

if you aren't then it's more expensive... the firmware is oss and the circuit provided

it's a bunch of shift registers 74hc595 connected to an atmega8
if you port it be aware they use a 14MHz quartz versus arduino uses a 16MHz quartz
