If I'm not mistaken, the Frieden brothers say they have an SMP capable kernel as well.
From the description you pointed to, the system sounds similar to an ASMP OS.

We've always know something like that could be kluged.

MorphOS could easily use each core as a separate environment (each with its own scheduler) with a common display via an enhanced Ambient.
But is that SMP?

I'm not trying to be a downer here.
I'm sure our developers have thought about it, but they seem to want to switch ISAs before they tackle multiprocessing.
