I have basic syn/ack (for lack of a better term) support for boxes sent through pipes, but I haven't yet written the code to allow sending only bodies. That should come in short order.

I started implementing a compatibility test for our implementations and ran into the following initial issues:
1) You don’t appear to be setting the default cv=zeros[CV_LEN], so the ‘extra’ argument to the first KDF is zero-length instead of 48 null bytes.
2) It looks like the t[0:32] bytes in your KDF are not that of the previous iteration.
3) I think what you are calling the ‘peerEphemeralKey’ is the recvr_pubkey. My understanding is that this is actually the long-term public key of the peer.
Trevor, please correct me if you see any inaccuracies in my reading of the spec.
