I am the lead maintainer of go-ios a OSS project to work with iOS devices that heavily relies on networking code. For this and other projects I built and maintain WebSocket, WebRTC and other networking production services. Recently, the need arose to run a full blown network stack as part of the project entirely in user space.
Google gVisor implements its own network stack called netstack. All aspects of the network stack are handled inside the Sentry — including TCP connection state, control messages, and packet assembly — keeping it isolated from the host network stack. While the primary use case is sandboxing containers, you can use netstack to run your own userspace wireguard network interfaces without installing interfaces, drivers or system user privileges.
Learn how companies like fly.io or tailscale build VPNs that do not require `sudo` by creatively
using Google's powerful gVisor netstack.

This is a story about how I reverse engineered Quicktime screen recording, Xcode test execution, built reverse engineering tools myself, created a small community for my 2 open source projects, stayed motivated for over 5 years and why Go was a great choice for all of this.
