Learned of this via TFTC h/t @mattodell ;
there's a short video demo and a slide deck, basically this is a mobile-to-mobile BIP78 payment implementation (interestingly, seems to be iPhone) using onion service for receiver as Joinmarket does. Was part of an MIT hackathon.
Most interesting if this BIP78 implementation makes its way into production mobile wallets, will be a great selling point ...
