Which codec will you use for VOIP and will we be able to stream data from Spectrum into the game like for example opening the forums with MobiGlas, receiving private messages in game and will it be secure?
TL;DRVOIP will use Opus, and Spectrum is meant to work as a deeper in-game overlay and backend service for some UI elements, but not appear inside the MobiGlas; security was not addressed.
Opus. The goal is to make it so you can access stuff in game, but not inside the game. It may break immersion a little bit, but they need Spectrum to be an overlay in the game because it would be tedious to go into MobiGlas and then go into a separate window and then so on and so forth. Think of it like a Steam overlay or a better example is the Curse overlay, but deeper.
The advantage they have with Spectrum and Star Citizen is that they are the game and instead of slapping an overlay on top of the game they can go deeper. Some elements of Spectrum will be used as backend services from within the game, but don't expect you'll be able to pop your MobiGlas and you'll see Spectrum in it, that's not where they're going, but you will be able to pop certain UI elements that use Spectrum behind the scenes. So for example the ability to use channels that are shared in game and out of the game.
