I agree a modified kernel will be what it takes to really unleash this beast but I don't doubt that some nut hasn't already started looking at what can be tweaked to make it happen. I'm pretty ignorant on this but aren't there "multi-core" PPC already or is that multi-processors? Macs have some dual processors and I'm sure SMP isn't hard to translate to this cause... I could be wrong I'm pretty ignorant about the multi-core stuff and how it relates to SMP or whatever. Basically I'm talking out of my ass on this one
