I made an IPFS(the torrent+git+ thing) based fork of this because of these reasons.

It uses IPFS gateway setup in local network, this enables: * Caching of downloaded data (this is useful when using it to boot multiple computers in one LAN) * More trust: boot menu is served from local IPFS gateway using immutable hashes. It is also really easy to review it by hand. * It's a bit more service-dies-scenario proof

Downsides include lack of better documentation and messy code in places - it's a large scale refactor that changes the basics of how the tool works and isn't quite polished. It lives at https://netboot.devtty.eu/. There is no set-up instructions(tr;dr setup: run lan-open ipfs gateway, add A dns record 'ipfs.local' pointing at it in your lan DNS server, rest like netboot.xyz).
