Expand the We The People petition system to include an opt-in voting system for private groups. Government would not enforce anything except identity and an official oath for each group.
Create USB sticks for keyrings to use in normal computers and distribute them like ID cards, the first one free.
To join a group, click a button to make an official oath as if in court, that the membership statement is about people like you.
Each proposal chooses standard or USB security, if names are published, yes/no or median vote, if votes can be changed, and public or private view.
Yes/no votes and statistical distribution of median votes display in realtime.
Recent protesters have been criticized for not agreeing on what they want. Lets give everyone a secure way to agree on things.
