I'd also suggest looking at the Freescale MPC line of embedded Power PC chips. Some of them have many multiplexed ADC inputs built-in along with a method of automatically queuing up which conversions you want. I think there are some with USB support, and I also think that there are ones which can do several 100 MIPS.
