An instructiable opened my eyes to the fact that an old Android phone can be used as a webcam (http://m.instructables.com/id/Make-A-Wi-fi-Webcam-From-An-Old-Android-Phone/) but instead of an IP camera I used the uStream app to make my 3D printer live broadcast at http://www.ustream.tv/channel/joes3dworkbenchThese models I don't see being particularly useful to anyone else unless you have the same phone I do and the same 3D printer I do, but maybe the idea will inspire someone.
