The little sysadmin in the back of my head says 'no', but I can see this sort of thing being very useful for small projects.

For companies with security and/or compliance needs, or paranoid people like me, it's more-or-less vital to keep development and production separated, and to firewall the hell out of what production can actually go out and get, as well as to tightly control who and what has access to the servers.

Most systems like this make the assumption that you've got full root-level access via SSH, which is often not the case. Likewise, I don't see anything for handling multiple servers (maybe I missed that?).
