Live Call In

So most of you have seen the first ever Video show. A few minutes ago an idea came to me. My friend sent me a link to his Ustream channel and an idea popped in my head. What do you guys think about a live call-in show where we have guests and live callers and take questions? We could do it once every couple of weeks as we interweave it with the existing video show. Just a thought! I figure since Facebook is such a hot topic there should be a live discussion. I know there probably won’t be a ton of people listening at any given time but I figured there could be enough viewers to have at least a 15-30 minute show. Thoughts?
