What you need to do:

* Use host_string instead of hosts. See the docs for a quick
explanation of how/why this works and env.hosts doesn't:
http://docs.fabfile.org/en/1.1.1/usage/library.html#connections
* The gist is that env.hosts only works when set *before* the task is
executed. Either at module level or by a non-remote-executing task run
on the CLI prior, e.g. "fab setup realtask".

What I need to do:

* Add this to the FAQ :)
