Hello,
Excel 2007 already does parallel computing.
A spreadsheet program internally creates a dependency graph

Gotcha. So Excel's formula calculation is already multi-threaded. This
is an area we should still work on to improve with Calc.
The idea has of course come up before (see
http://wiki.services.openoffice.org/wiki/Calc/Performance/misc), but it
hasn't been evaluated in much detail yet.
