It looks to be equivalent to Esri's 'branch versioning' on their proprietary ArcGIS Enterprise product, but can also deal with flat files as well as geospatial databases (PostGIS), which while not strictly required becomes really useful when dealing with edits, and conflict management, across multiple editors in large enterprise organisations, such as those that deal with state or country-wide mapping of topographic features.

If it integrated with QGIS/ArcGIS to show visual differences, and allow a user to easily reconcile differences between conflicting features (based on topological rules), I'd definitely be interested though it doesn't seem like it at a glance.

@fyrn_ Re: the work you did with 'multiplayer map editing', is there anything public you could show? I'm interested in how you solved this challenge.

Sadly nothing I can share publically. I work for an AV company
