But that's the nose config, not a pylons config.

test.ini is referred to in the tests/__init__.py. I guess you're thinking of
'nose --with-pylons=buildbot.ini', but then you have to replicate all the
rest of the test.ini options (apart from the sqlalchemy one) in there. You
also have to work out how to tell the other pylons instances that tests
start independently to use this other config file. So I don't see it as
simple as you suggested.
