Possibilities..

This is an awesome looking project Dennis. I wonder how much work it would be to adapt the codebase to replace Leaflet with a simple white background, and add option to place and format text labels? You'd then effectively have the world's best open-source collaborative mind-mapping app. Basically etherpad with full flexibility on content location in the page-space.. Do you have a sense of how much work that would be to achieve?

That sounds like a cool idea.
Simply removing the background map wouldn't be too hard. For labeling there are some leaflet plugins available.
One example would be Leaflet.label (https://github.com/Leaflet/Leaflet.label/blob/master/README.md)
If the map context isn't used at all it would also be possible to completely exchange the leaflet part with a library for mind map. That would obviously be more work.
