Health Care "Call In" Town Hall Meeting

I read today (here) where Congressman Yarmuth held a health care "town hall meeting" over the phone. They allowed people to call in and ask questions, but only after they were pre-screened. All of his fellow legislators are holding live town meetings and apparently taking a lot of heat over opposition to the health care plan. It didn't take Mr. Yarmuth long to figure out how to hold a town hall meeting in a way to avoid any controversy.
