I found an update for SuperBeam, or at least that's what I thought. It turned out to be something called Sharecloud, and when I scanned the other phone's SuperBeam QR code, all it did was lead to the download page for Sharecloud. What is Sharecloud, how is it related to SuperBeam, and is either of them any good? I also wanted to say goodbye to crashdamage, who has offered a lot of good advice.
