We have one something like that at the hospital I work at. They've been around for a while.
Ours keeps breaking down 'cause our net connection is so bad,
Needs a dedicated line to make it work better I think.
But, yes, they can be good for folk away form home needing to email other folk and stufff. Had a guy wanting to send pics of his new baby from his cam - IT folk said it was a non-no though.
Cheers
