The best way to work around it for now is to mutate env.users to prefix the host strings with "username@" instead of setting env.user, e.g.:: def user(name): env.hosts = [name + "@" + x for x in env.hosts if "@" not in x] In other words, it would change ['host1', 'host2'] to ['name@host1', 'name@host2']. env.user only really works as intended if set at module level instead of at runtime (IIRC; it's been a while since I touched this part of things.) This isn't a very good design and will definitely change in future releases. There's work going on now to make tasks more object oriented, for example, which will straighten a lot of this out instead of relying on env to be both informational and for configuration. > The next question is, is there a group of people that are sharing best tips, > etc. for using fabric on cloud based systems?

No specific group, but I would definitely welcome discussion on that here, and it comes up on IRC relatively frequently as well. I'm personally using more cloud stuff now than I used to, to say nothing of the increasing amount of user contributions in the same space -- so improvements should come along relatively quickly.
