What I call "VoteFair negotiation ranking" is available at:

www.NegotiationTool.com

This calculation method does not consider political parties or districts 
or anything other than ranked priorities and incompatibilities.

It goes beyond "VoteFair representation ranking" which is a multi-winner 
method that also does not consider districts or parties.  Specifically 
the negotiation tool goes beyond the one-dimensional nature of VoteFair 
representation ranking so that it handles multi-dimensional issues.

Picking pizza toppings could certainly be handled by the negotiation 
tool.  The two demos are for more challenging cases, namely negotiating 
hiring terms, and assisting a Parliament in choosing a set of cabinet 
members.

(A few days ago I moved the NegotiationTool website to a different 
server, and the "contact" form doesn't yet work there yet, but it works 
otherwise.)
