I admit that I haven't read all the messages in this discussion. I probably missed the beginning. So, I'm wondering where this is really going? Is there any real possibility that someone is interested in actually developing a new device, or is this just a dream? If someone has come concrete ideas about how these wishes might be accomplished, is there any idea of where funding would come from?
