100% doable and easy. In clients like qBittorrent you can right click on a torrent and select both "Download Sequentially" and "Download first and last pieces". Once it downloads the first and last pieces, you can wait for a bit until maybe the first 5% has downloaded, and you can open the file with a decent video player like VLC, and as long as the download is faster than the play speed, it'll play just fine.

Same here. Bite arden is great, better than Dashlane and it's FOSS.

Also came from Apollo, but 20 days ago, when shit started hitting the fan.
