> What person would ever want this "feature"?

The disabled come to mind, for starters. The elderly, assisted living, I can think of a few use cases.

Do you remember the Nextel phones? (push to talk) They were annoying as all hell in a corporate setting, but had some very valid use cases in a lot of industries, to the point of being the #1 feature of a Nextel.

There are definitely use cases for them. I was talking to a nurse the other day who was trying to track someone down on campus and she lamented "I wish we could just go back to our old Nextels".

Given that both sides of the link are fixed, rather than mobile, devices, Nextel phones aren't quite the right comparison here. Essentially this is a video intercom.
