There's no relation to magic-wormhole. wormhole.app is an independent design and implementation. It's a similar in spirit to Firefox Send (and uses the same ECE streaming encryption that they did). Our design supports instant streaming (instant share link, downloader can start downloading before upload is finished) and peer-to-peer transfer (based on the WebTorrent protocol, which I created).
The word "wormhole" seems to be used in many different tools. For example, try running `brew info wormhole`. You don't get magic-wormhole or wormhole.app but something else entirely.
