Sorry, I see from an earlier message of yours that you are looking for a simple non-crypto solution, so I guess this doesn't fit the bill. The examples you gave in your earlier message all seem to be equivalent to having the participants send the data to a trusted third party who performs the computation, except that the trusted third party is transplanted to one or more of the participants computers, which are protected against their owners. I guess it boils down to whether or not the level of trust is sufficient. This seems iffy when one of the participants is also the trust provider.
