I love this project and I hope will succeed. I am thinking to bring yggdrasil in the mix. That network works pretty great and the fact you can generate your own IPv6 from ed25519 keys is awesome. With these two you can setup a network however you want. Ygg is giving the metwork, pubky the dns and resolve. At this point you don't even need k8s, goes with out saying cloud monopol can finally be teard down. 

There are tones of applications, you can do anything. From end user apps to low level such as db, file storage. All is possible now :) 

 I am aware of Yggdrassil and I tried it myself, works well.

I don't have any specific plans to use it, but I think Pkarr can help Yggdrassil, and I would be happy to help the Yggdrassil team or anyone who wants to hack them together. 

We already can use upnp or hole punching to run servers from anywhere, but Pkarr is not suited for records that change often (caching and TTL is important for scaling) so anything that allows servers to have stable endpoints is welcome. 

 Yes, exactly. They can work as complements.
