Note that it will download around ~300Mb of data directly to your browser, so it might take a bit to load from slow connections.
Here's the related video from FOSDEM: https://fosdem.org/2022/schedule/event/lotech_lowa/
Even with a fast connection, it takes a very long time. I'm guessing the site is overloaded as the peak was a few tens of Mb/s, and generally much slower.
Makes me wonder if it is possible/usefull to make the download a two step process, first download a small wasm bittorrent client, then use it to download (and share) the 300mb file.
Webtorrent already exists, and does not require wasm.
