A third question (actually, I think two questions) was about protocols for democratic participation in coops. We have occasionally used polls for getting the temperature of the membership on CoSocialCa, and I know that social.coop uses loom.io's features for voting on some issues. But at least with CoSocial, we haven't invested too much time or effort into cryptographic, anonymising voting systems. We get most of our voting done by show of hands!
