I heard that some people in NY started coding up a voting system, similar to http://en.wikipedia.org/wiki/Proxy_voting Is that true? If yes, could somebody please point me to that team? Maybe it would be better to combine forces and work and improve existing things?
There already exist several such projects, two important ones i know of, that are already pretty well-thought-out and stable. They are already in heavy use, i.e. by a the "pirates", a new party in germany that kickstarted to almost 10% and they base themselves on the ideal of "liquid democracy". Several other parties and dozens of associations use it, also some public institutions.
There are at least two such systems:
adhocracy: http://trac.adhocracy.cc and http://liqd.net/en
"liquid feedback": http://www.public-software-group.org/liquid_feedback and http://liquidfeedback.org/mission/
what are your particular goals? I heard you want it to be decentralized? We might find a way to adapt the existing ones. They both use sql, but we might find a way to distribute I.e. some distributed file system, or some NoSQL that speaks sql.
