Hi Jacki,
I just got the last pieces done to complete the core functionality of
the messenger service I'm working on for a while. So it is updated on
the main branch now and can be build by enabling the experimental flag.
(I think it's best letting it experimental until a next major release.)
I just found your thread. Thank you for your wonderful work.
I don't know what your protocol looks like, but please consider the needs of people using airgapped sneakernet in future design work. Not everybody can keep data uncompromised on a networked system. PGP and I believe Signal are workable across sneakernet, but secushare didn't design for the usecase, requiring networked keys.
Regardless, the world needs a core peer to peer messaging system, and anything you can publish is incredible.
Be well.
