From your description I am missing one important idea that you should communicate clearly: you, we and nobody else currently wants to have online voting - what we want to have, are tools that enable transparency and gathering of information, also discussions and preparation of decisions, but the final decision is something you do NOT want to do online.

See this talk from 31C3: http://media.ccc.de/browse/congress/2014/31c3_-_6344_-_en_-_...

If you still believe that online voting is doable and a great thing, please contact Mr. Halderman and talk to him or read about his work: https://jhalderm.com/

Also I recommend to do some research what the german pirate party is using regarding democracy tools - they have a lot of experience not only coding such tools, but also with real life usage.

A good start could be https://liqd.net/en/ here you can find the adhocracy platform: https://github.com/liqd/adhocracy/

which seems to be in a much better developed state than what I see on democracyOS - but maybe there are many things not visible right now to me, so sorry for this criticism.

Adhocracy is currently in use by several organizations and they have lots of real life experience, especially with user adaption.

An interesting application of adhocracy is https://offenekommune.de/

Another interesting tool for organizing (really big) meetings: http://openslides.org/en/

and of course the brilliant idea of Bundes-Git, a law-making platform: http://okfnlabs.org/blog/2012/12/13/bundesgit-german-laws-on...

Maybe the best way to get some overview would be to contact the awesome people at https://okfn.org/ - good luck!
