Any suggestions for maintaining sound and video quality when you are interviewing/featuring someone remote, who does not have any special sound or video equipment beyond what they have on their laptop? Would you keep a modest kit with decent webcam and mic that you can mail them with a return label? I've heard of at least one podcaster doing this. The comments here were as helpful as the original post - thanks all.
