Deploying an instance of a written-in-Rust social network by:
1) $ cargo new instance_name --bin
2) Editing Cargo.toml *
3) $ cargo run **
*) The Cargo.toml file would list a set of social network building blocks as dependencies, and include all necessary configuration (e.g. domain name)
**) starts the server in the background.
I don't know if this is possible or just insane, but that's really the level of flexibility I dream about in a social networking server
