might demonstrate what you're looking for as well.
I don't believe there is an existing way to send messages longer than CONNECTOR_MAX_MSG_SIZE. Perhaps you could send multiple messages with the same sequence number but a different "fragment number" in the message.
However, if you're sending messages much larger than CONNECTOR_MAX_MSG_SIZE perhaps the medium of communication is not appropriate. Have you considered relay files?
