Miguel,
regarding your friend's neural network, I suspect that PIC is not an
optimum solution as pic is primarily designed as a microcontroler.
Memory limitations on microcontrolers will severely restrict your
ability to compare or even to store video frames. Even the 17Cxxy series
is not friendly to addressing external memory, and you would be using
macros instead of single instructions for off chip memory.

If you can accept the higher cost, then you could look at something like
an ST10 series micro from SGS Thomson (100k Flash ROM varients
available)
