Hi Sleg,
the basic services (WMS/WFS/WCS) can only return information
that's already there, they are bound to a fixed information schema.
If you want to perform computation you either get the data client side and
do the calculations there, or use WPS, either using the built-in processes,
if they suit you, or writing your own

Cheers
Andrea
