Well, as mentioned all get() currently does is append a suffix, but
otherwise you should have full control over the local path and name.
If it's not working as expected (e.g. passing a full relative or
absolute path as ``local_path`` is not working) I'd be interested in
the circumstances :) All we do is use paramiko's sftp.get() method,
which I imagine is pretty flexible in this regard.

You can pass in the username in host strings, e.g. address@hidden,
address@hidden, etc. This will work anywhere host strings are accepted:
the global -H command line parameter, or per-command options (fab
foo:address@hidden) or in-fabfile setting of env.hosts, and so on
and so forth.

Passwords, you should always be prompted every time a different remote
system asks for a password, and while you *can* press Enter to use the
last password entered, you may always re-enter a different password.

So if you're looking at 3 distinct hosts with 3 distinct usernames and
password combinations, you should be able to do:

    $ fab -H address@hidden,address@hidden,address@hidden do_my_stuff
    ...
    Password for address@hidden: <enter user1 password here>
    ...
    Password for address@hidden [Enter for previous]: <enter user2 password 
here>
    ...
    Password for address@hidden [Enter for previous]: <user3 password>

If there's an angle I'm missing here, let me know :) Note that there
are plans to have per-host settings be much more robust than this,
including the ability to specify individual per-host passwords before
the fact and thus not have to get prompted for them at all.

I'm guessing this will be in for 1.0 (0.9 final should be out
relatively soon and no big new features are going to appear for it.)
