I needed support for "priv" instead of Fabric's built-in "sudo" support. I went through a number of (sometimes quite horrific) iterations before I settled on this relatively simple solution:

import contextlib

@contextlib.contextmanager
def priv(user):
    '''Context manager to cause all run()'ed operations to be
    priv('user')'ed.
    
    Replaces env.shell with the priv command for the duration of the
    context.
    '''
    save_shell = env.shell
    env.shell = 'priv su - %s -c' % user
    yield
    env.shell = save_shell

This is then used in a fabfile like so:

    with priv('remote_user'):
        run('do some remote command as remote_user')
        run('another remote command as remote_user')

The 13th Python Game Programming Challenge (PyWeek) is coming. It'll run from the 11th to the 18th of September.

The PyWeek challenge:

1. Invites entrants to write a game in one week from scratch either as an individual or in a team,
2. Is intended to be challenging and fun,
3. Will hopefully increase the public body of game tools, code and expertise,
4. Will let a lot of people actually finish a game, and
5. May inspire new projects (with ready made teams!)

If you've never written a game before and would like to try things out then perhaps you could try either:

1. The tutorial I presented at LCA 2010, Introduction to Game Programming, or
2. The book Invent Your Own Computer Games With Python
