Having to install a plugin is kind of annoying, but Voxli is one of the simplest-to-setup, easiest-to-use voice chats I've ever used. Inviting someone to a chat via a URL is really convenient and I could really see this taking off.
Glad you find it simple. We don't like installing plugins easier, but gamers need certain features that we couldn't provide with what's built into Flash--like push-to-talk from any application.
