It might. Using Opus does not equate to low audio latency. (I don't actually know Opus, but I have passing familiarity with it's predecessor speex). Assuming Opus has the same design goals as speex, Opus gives you the tools necessary to implement a low-latency audio application. As in - the audio codec piece is "solved", now you need to do the engineering work around client/server/framing/network etc. to actually get to your latency goals.
