At P4P Berlin we talked about various protocols that partially overlap in goals with HyperHyperSpace last weekend. Would be nice to have a more detailed comparison of how HHS fits into that and compares in features with other protocols! Does such a comparison exist already?

Also, I remember two years ago at Ink&Switch Unconf in Berlin we had a discussion about how to kick someone out of a group, and then yesterday this exact topic came up at the Local First online meetup:

How do those "signature chains" compare to what HHS does? Would love to chat more about this!
