Hi,
At one of the OOo conferences I vaguely remember there was a university project that already parallelized computation of Calc sheets. Unfortunately I cannot remember the project/university name anymore. Probably having a look at the conference session drafts might give us some more insight.
...it wasn't directly about parallelization but about using Calc as a frontend for grid computing. I've found the conference abstract about the Tavernalc project on the OOo Marketing conference page of the conference in Barcelona.
