RTCDataChannel.send(Blob) is now implemented and the onMessage event can now optionally receive data of type Blob using the binaryType attribute. In addition to supporting sending strings and ArrayBuffers, you can chose to send a Blob instead as long as its size is below the SCTP transport maxMessageSize as indicated in the WebRTC specification. Using the binaryType attribute set to "blob", the onMessage event data attribute will be of type Blob instead of the currently supported ArrayBuffer.
