What problem is this solving? Normally things like transit don’t have encryption because it occurs at a higher level.
To me it seems advantageous to keep the pipes dumb, curious of the rational behind this.
You have two machines on networks you don't know/control and no established identities/accounts. You want to pipe some data between them without setting up a more permanent network like ZeroTier with SSH or other access.

OpenVPN, IPsec, nebula, ZeroTier, Hamachi, and many others would disagree.
Wireguard:
+ Can tunnel arbitrary IP traffic
~ Has stricter encryption, with full asymmetric keys (and optionally adding a symmetric key)
- requires permissions to load a kernel module and configure the network stack
Hyperbeam:
+ Only needs userland UDP sockets, not a kernel module
~ Derives its keys from a passphrase, so does not require transferring a full cryptographic key between devices
- is a single application-layer pipe, applicable in shell workflows but not transparently tunneling arbitrary applications
this has nothing to do with that, to me this looks like the same general concept as using netcat (nc) to pipe text, but with auto discovery and encryption.
