Grain-of-salt alert as I don't own a 64-bit system ...

Not me, sorry. Others may be able to help here.

As I recall, I meant that in a somewhat sloppy sense that Quantian and
openMosix could combine several 64-bit machines in a 32-bit cluster which
could still outperform running a single 64 bit machine running solo.

Fair point. I heard that the 64bit machines like more ram, everything else
being constant. They are said to be fast, and may well be "future proof".
On the other hand 32-bit works well so I'd probably stick with that.
Hope this helps, Dirk
