This would be useful. Currently similar index list is located in turbogears
project, and while some new packages are already on tg2 index, some are not. You
get an error if the package can't be found, so having a second index I could
point to would allow for a "fail over":
From reading setuptools it seems as this would be a recommended setup.cfg
configuration.
[easy_install] 
index_url = http://turbogears.org/2.0/downloads/current/index/
            http://pypi.python.org/simple/


Let me know which version this gets implemented in assuming this patch allows
for a configuration I just specified above.
Thanks,
Lucas
