Social Conference Calling

It looks like I’ve learned about another technology out there called Social Conference Calling(SCC). I may be a little behind on this as people have been doing this in Second Life for a few years now. Basically it is a gathering of people talking to each other over the internet, phone, or both. I am interested in this technology in order to create a live podcast in the virtual world of SL. I found a site that does this called Talk Shoe. The problem is that I need a url for an exposed audio stream so people can listen in through SL. I may have to end up streaming with an alt account through two-way voice chat so that people in-world can be included in the conversation. I will keep researching
