I think the consensus part of Paxos is more important than the robustness in the face of byzantine treachery. My selfish goal when I proposed this project is to by the end have a system, or be on the path towards a system that works like
http://openreplica.org/ but implemented in Smalltalk. It would be nice to be able to easily create robust, distributed server applications in Smalltalk, and hopefully have a tool that many can use with little configuration other than pointing images at each other or a discovery service.
