We publish federated wiki software as a Node.js package ready to run on a variety of platforms. This is usefully run on a personal laptop or an industrial server in the cloud. viki.wiki supports a multi-tenant "farm" option useful for small groups or heavy users. npm 
Federated Wiki offers some independence from the market-ready representation of the artist while maintaining the protocols that make institutions (people, documentation) possible.
