Myself and a lot of people i know play World of Warcraft (WoW). This game, and many other games use an app called Ventrilo or Vent to keep in touch with teammates.
Does anyone know of any info on this, if there are API's available, or if any dev's are currently working on such an app?
Ventrilo - Surround Sound Voice Communication Software
I would say an app like this would absolutely sell very well, even with a decent price like 5.99 or so. Im sure many people would buy it which makes it very much worthwhile for a developer to explore.
