// The SctpTransportProxy class takes care of thread-jumping when
// connecting callbacks from a webrtc::SctpTransport to a
// blink::RTCSctpTransport object.

// Its design is modeled on the IceTransportProxy design,
// but does not use so many layers of indirection - there is
// no control, and all information is passed via callbacks on the Delegate.

// The proxy thread = the Blink main thread
// The host thread = the webrtc signalling thread (the one that gets callbacks)
