So I'm trying out a new voice chat setup, called Discord.
It seems pretty nice. I setup a widget for people to use to try and connect with -- feel free to mess with it by clicking connect and setting up an account -- and seeing how things go.
I'm still learning how this works, but so far it seems like a pretty decent setup, and once the API is ready, I could potentially set it up so the chat on the website is integrate with the chat in Discord. It has chat channels like IRC, as well as voice channels -- SiN is apparently using this.
You can have multiple channels open at once too, which is nice, IE I'm connected to my Saecula channel I created, and the SiN channel. It apparently has a pretty decent mobile app too, check it out.
Or click the widget on the main page.
