You mentioned that a pic probably wasen't up to it previously, but it really doesn't need to be part of the actual aquisition circuit using the techniques shown in the video digitizer. Fill up the FIFO using a HS clock, use the pic to poll the ram and send it serially; like the bitscope... Actually he does have a 20MHz generic sampler somewhere on that site...
