I forgot about those recordings. Man I sound so stuffy. Anyhow, yes, clients are the part I haven't even started yet. I'm working on the spec, the core libraries, a server, and a master key manager, but I haven't started a client yet. I'd recommend using mosaic-core (from another language if you would like -- tell me which and I'll make it accessible to that language), rather than starting from scratch. Eventually multiple independent code bases will be a good thing to have, but probably since we are so early, better to not duplicate work so we can get it running sooner. You can get started looking at mosaic-core, first the examples, then the test cases like test_user_bootstrap_dht().
