There’s a strong air of grantware to it. The notion that it could be end-to-end auditable from the RTL up is interesting, though, and generally Wireguard performance will tank with a large routing table and small MTUs like you might suffer on a VPN endpoint server while this project seems to target line speed even at the absolute worst case routing x packets scenario.
The project got a grant from NLnet. I think they do a great job, they gave grants to many nice projects (and also some projects that are going nowhere, but I guess that is all in the game). NLnet really deserves praise for what they are doing!! https://nlnet.nl/thema/NGI0CommonsFund.html
Academic projects which receive grant money to produce papers and slides. This still can advance the state of the art, to be clear, and I like the papers and slides coming out of this project. But I wouldn’t cross my fingers for a working solution anytime soon.
