It seems rather likely this material has been discussed before. But I'll jot these thoughts here as a placeholder for my own further inquiry.
There's a very natural flow in editing and re-arranging paragraphs. And I already see that there are tags on at least some of the wiki plugins in github. Has any thought been given to how a paragraph might request a particular version of plugin?
In a separate experiment, I've begun work on a plugin for turtle geometry within federated wiki. I've run many experiments in turtle geometry from my weblog. One area I've daydreamed at length and then pined away for sufficient time to pursue... better collaboration and sharing of turtle programs and shapes.
I'm quite convinced that federated wiki is *exactly* the collaborative foundation I've dreamt -- versioning, sharing, forking, and side-by-side display for comparison, contrast, and synthesis.
