To make it indistinguishable we’d need a metadata-leak-resistant protocol for encrypted messaging that breaks them into indistinguishable streams of messages of a fixed size. Maybe the HRF bounty #3 for encrypted chats should take this in mind. If there were encrypted application protocol bits in such a protocol it might be possible to do a arbitrary secure transport protocols inside rather than being for pure chat.

I’m not sure how to make it backwards compatible with v1 http senders and indistinguishable yet, since an adapter would be able to distinguish pj as those requests over http. But there might be a way if the adapter has another general purpose function 🤔
