@noffle: "Re cyptocurrency in SSB: Are there risks to bringing a money layer to SSB? I can't help but think about the hurt and emotional challenges that the SSB grants brought to the community, and wanted to pose the question. Money seems to have a way of bringing out certain value sets in people."
Agree with all of what you've said noffle. Should clarify that the ssb component is about interdependent social backups. In our case we are making use of this affordance and possibly planning to weave this into a social multi-sig.
The same protocol could be used for any sharded secret (such as .ssb/secret)
The wider discussions about Money are certainly worth having as well.
