I'll CC this message to the VIFF mailinglist as well -- there are many people there who can help you if I cannot.

My guess is No, but I am not not sure.

I'm sorry, but I'm not familiar with that paper. But you should think of VIFF as having a number of layers: 1. basic player administration 2. network setup 3. secret sharing and reconstruction (Shamir-based) 4. secure addition and multiplication 5. more complex protocols So depending on how the primitive above fits into the stack, you may be able to reuse more or less code. > Sorry if my queries don't make sense.
