Using roles is currently considered to be the "proper" and "correct" way of doing this and is what you "should" do it.

That said, if you are like most of what you "would like" or "desire" is the ability to perform a "twisted syster" or switching target systems on the fly.

So for entertainment purposes only (!) the following example illustrates what many might consider to a risky, and yet somehow thoroughly satisfying, manoeuvre that goes something like this:

env.remote_hosts       = env.hosts = ['10.0.1.6']
env.remote_user        = env.user = 'bob'
env.remote_password    = env.password = 'password1'
env.remote_host_string = env.host_string

env.local_hosts        = ['127.0.0.1']
env.local_user         = 'mark'
env.local_password     = 'password2'

def perform_sumersault():
    env_local_host_string = env.host_string = env.local_user + '@' + env.local_hosts[0]
    env.password = env.local_password
    run("hostname -f")
    env.host_string = env.remote_host_string
    env.remote_password = env.password
    run("hostname -f")

Then running:

fab perform_sumersault
