Hi, yes, I will publish the C++ code as open source.
In the meantime I succeeded (hopefully) in uncovering the binary format used in the RPC. Seems that every message starts with a 4 byte integer in little endian notation. It describes the size of the message. Then follows a varint serial number (meaning not totally clear to me currently) as a varint (see protocol buffer definition). Next is a varint which describes the length of the function-name. Next is the function-name. Next is a varint which determines the size of the payload. The payload itself is a normal protocol buffer. That's it. The next message follows suit. However, I did not implement this, so it might still be wrong. At least the format seems to be rather straight forward.
