I think it is an interesting idea that has yet to gain traction, let alone interoperable implementations, possibly due to the cantankerous origins. May have difficulty penetrating the enterprise, where control of policy trumps most other considerations. And as with any multi-sided business model, it requires a community segment with unmet needs to provide initial critical mass. I suggest trying to make the protocol less binary and more like a classical line-oriented exchange, it'll improve uptake amongst implementers. And I wish you well; every effort to reinvent email deserves a red hot go.
