Neat project! Sounds like it has a very different ethos to mine though:

> This container mounts a read-only copy of your current path at /src as a non-root user and restricts network access to a select list of http and https destinations. All other network traffic is blocked.

Yolobox mounts the current directory in read-write, the default user has sudo, and there's full network access by default. You can disable network access with `yolobox --no-network` if you want.
