Hi Gordon:)
If I remember correctly I actually tried this but found that it was not worth
it.
The sorting step is actually fairly low cost compared to the large cost
incurred by the SPH calculations (due to the amount of imperfectly coalesced
memory reads in the neighborhood particle lookup).
Using a grid with larger cells would mean that more of the particles outside
the smoothing length would have to be checked (and discarded),,
Now that a new and even better radix sort exists
(http://code.google.com/p/back40computing/) this should be even more true.

Following as a logical conclusion to this it would be interesting to see if the
new sorting could would make it advantages to use an even finer grid..
