The Remote tab lets you connect your media to a device that is not in your current location (e.g. your computer or media server at home).
You are not able to control your media remotely, but you can make the connection. Here's an example of where this may come in handy.
You have two computers, both with Skifta and both with media on them - but you are not close to either of them. Using your handset, you can connect the two computers to each other, one as a source and one as a destination. Then, someone at the destination end of the connection can access the source device and play the media.
All without you having to be close to either.
