A highly anticipated option would be the ability to add voice instances, so that whatever channel you are on, you could be connected to another voice instance based on the best parameters for the user, permission data could be provided via API/Socket from the base in real time. This would increase fault tolerance because the server would not be set in stone, and it would give flexibility to the intercommunity.
The Matrix (formerly riot) protocol that the teamspeak 5 version uses enables such elements, but whether we get such capabilities as self-hosting would be nice.
