Zero latency audio is a physical impossibility with contemporary computer
hardware and drivers, so that's that.
Now that being said, there are no proposals so far how to configure output for
low latency, or indeed the entire pipeline in general. It's not infeasible,
but it's probably several human-years of full time work to get right.
