Sending a mix stream without adding system latency?

Sorry, I may have been unclear. I’d like to setup a live connection as with the Steinberg iOS app Studio Pass. The description says:

“Let your client dial in with an iOS device via Internet and send the mix live to the mobile device in order to receive the feedback needed to get the job done, no matter where the client is that very moment”

Either sending the mix live to Studio pass or VST Connect Performer runs the system with latency.
