i think the other (turf-like) segmentation strategy is pretty common in earlier work. i wonder about the relative efficacy from a VM implementation standpoint. particularily wrt grant/revoke on a byte range rather than a segment.

the other thing that struck me as really strange was a bit in the question period where he says that 'smart devices' (DMA?) are different from simple devices (pio?) in that they are expected to be first-class multiprocessing citizens. doesn't that imply that high-performance peripherals need to be specially designed for the Mill? (likely with a Mill core attached)
