Why? With the host packaging system I get versioned packages, through host management tools I can control which packages my production, staging, and development hosts should have, and I can describe my dependencies on host libraries and software through the host system's own tools.
Together with distribution systems like apt I can also significantly ease deployment.
I can see that executing some commands over a set of hosts at the same time could be useful, but doesn't sound like a killer feature for me.
As for deploying from staging to production servers, it sounds more tidy to build proper packages to deploy in staging and test before deploying the same packages to production.

- prodigal_erik 17y agodsh is worth looking at. It's essentially a for loop that runs ssh, but it can also get named groups of machines from config files, run them in parallel, and prefix output lines with the machine they came from.
