I'm a co-founder/dev at PowWow. VoiceChat is going to be in the next major release. We already have system audio being ogg/vorbis'ed to you so its not a question of expertise but simply time allocation. I completely agree that whenever we have PowWow'ed, we would have a active skype session since that's much easier than chat. That's also what a alpha release is supposed to be - to gather your inputs! So if everyone agrees that Voice chat is a must have it'll definitely be there in the general release!
Yup - we are actually using webRTC under the covers for video/audio RTP and webRTC itself uses Opus (or recommends) so we'll probably be switching to that for audio chat when we go that route. Thanks!
Do you have experience in using Opus for something else than speech? I'm currently in a project that deals with audio streaming and I've been exploring my options. Would love to hear about your thoughts!
