An ability to talk to all voice channels in the room from the main voice channel

The gaming community is wishing for this function for a long time. Most people still use TeamSpeak thought they don't like it, but just cause it has that particular ability: to speak to another voice channels in the category from the main one. This means, that if Discord would ever add this, it will receive tons of new customers, some of whom have been paying for an ability to use this for quite some time now. Lack of this functionality is actually what is stopping many communities from using discord for their needs.
