Plex is unclear on how to setup and configure. Plus the app takes up your whole screen.
There has to be an app that can read from your iTunes library and stream over the internet.
HamachiX does this GREAT from computer to computer over the internet..with almost no configuration...but has yet to connect to Mobile devices or an app that can connect to Hamachi servers on a mobile device.
I would strongly recommend programmers come up with an mobile app that communicates to HamachiX as a solution from home to mobile services. It's really built right in and ready to go.
That way we can all create our OWN clouds from our own home computers.
