Remote torrent download

Preamble

Sometimes you stand in a bookstore, you see an interesting book - but there is no money in your pocket, or friends told about the film, and you are not at the computer (for example, on pairs, or going home). Usually, in this case, nothing can be done except to not forget or write down the name, and then download.
But once I had the idea that it would be great to put something downloaded from the phone, come home and sit down to watch without waiting (let it wait a little, the speed is high, but still)
