Guys, unless I'm misunderstanding your feature request, I'm pretty sure streaming over cellular already works. Since you already have the server software installed, it should be a matter of forwarding the port number on your router (and probably signing up for a dynamic DNS service like dyndns or no-ip so you don't have to remember/keep up to date on your external IP). From the iOS app you would then add the dynamic DNS name and port in settings. I will say that this doesn't seem to work for HDHR Prime streaming, and I had to activate a VPN connection in order for that to work while I was away from the house.
