Unclear how to handle custom send() messages

[casept]

When I send a message from my script using send() like below, I'd expect it to be parsed as a SendMessage:

send("message", data)

Instead, it gets handled as a message of type Other, in a manner where I can't access the data payload at all:

Object {"data": String("{\"type\":\"send\",\"payload\":\"message\"}"), "error": String("invalid type: string \"message\", expected struct SendPayload")}

If I try to manually construct and pass to send() a JSON object that looks like a struct SendMessage, the handler is not called at all and the messages are silently eaten:

send({type: "READ", id: 0, result: "ffff", returns: "read"}, data);

Could be that I'm using it wrong, but I can't find documentation or code samples that go beyond the trivial "just print log messages" sort of use case.

Seems like it's just misleading naming and we're supposed to use Other. As for accessing the binary data, that seems to have been a missing feature and I've opened #186 to address it.
