Linux wifi/3g support so that you can run smartcam at command line mode. So you would be able to stream video from your mobile phone to your linux server which would be broadcasting it through web interface to multiple users. Your mobile can stream at wifi/3G connection to only one person at good quality. Also you can access http with almost any device with internet connection, they only have to know the url.
This is possible with windows machines, but usually when you have a situation you want to stream something to your friend, your home PC isn't powered on.
