Interesting! We're at a very early stage of the implementation and develop in rust. We aim to provide multi-sig capabilities, as defined in a JSON file where the public keys of the signers can be found. If a signer looses a key, we want this 'signers' file to be updatable with the new key. We decided that signers can be humans of processes, so the keys are not an identity of a person, which might be an important detail. Currently, to update a signers file, other members of the multi-sig must sign the update. This works fine, but we are early enough in the project implementation to explore other approaches, hence my question.

We'd rather not shell out to a cli, and would preferably go with a lib or rest interface.
