I built an open source userspace network stack in Go because standard Linux networking wasn't flexible enough for AI agents

I implemented Pilot Protocol as an open source userspace networking daemon to solve the transient identity problem for autonomous software agents running on Linux servers. I realized that relying on kernel-level TCP/IP stacks ties agent identity to physical interfaces and IP addresses which breaks mobility so I decided to implement a complete Layer 5 overlay network entirely in userspace that runs over a single UDP socket. The daemon manages a virtual network interface card and handles complex tasks like NAT hole punching and reliable delivery using a custom implementation of sliding windows and AIMD congestion control that I tuned specifically to handle the bursty nature of agent traffic. I handled the IPC layer where the daemon creates a Unix domain socket with mode 0600 to securely multiplex connections from local processes which allows you to run standard HTTP servers over the overlay without root privileges or kernel modules. Any feedback/ideas are greatly appreciated, Thanks.
