At least in arch, the package qbittorrent-nox now contains the ability to connect to i2p. For people starting out, using i2p you wouldn’t need to use a VPN to download your favorite “linux ISOs”; just use i2p and have a fully automated Jellyfin server!
I recommend using i2pd as the i2p router
Depends on your definition of very slow. I’m currently getting 1MBps which is alright.
