Correct me if I'm wrong Kim but
this is more a shader issue rather than a simulation thing.
If XSI had a good volume shader, we could achieve this result with both
grid-based and particles simulations.
I've once been told though that it's more difficult to implement the
"hypervoxel" or "afterburn" texturing features in MR
(because they are isosurface or someeeethinnng like that).

It's worth pointing out here, though, that motion for some of those particle
based simulations you won't get right XSI's particle system. In particular,
check out that one with the black smoke and fiery middle. If there's a
motion of it available you should see a really nice boiling kind of motion
which is very typical of big, explosive type effects. There's another nice
example on Glasswork's site which I think is one of their custom particle
effects, correct me if I'm wrong Alastair. Pete, wasn't it?
