How do TPL and mentioned here dn42 compare to Yggdrasil?

TPL: virtual permanent LAN party, closed group.

DN42: build a second internet to learn how it works. Public, no privacy features.

Yggdrasil: build a next generation Internet with some privacy features, and self-organization without central assignment

Tor/I2P: build a completely private internet, but sacrificing speed and the ability to operate on the base layer. (Yggdrasil and DN42 and TPL can run on individual one-to-one links, but Tor and I2P assume existing any-to-any connectivity on the layer beneath, which means you already need an internet)
