While it's obviously useful to not require PasteDeploy, this itself is
not true. You can use something like:
from repoze.bfg.paster import get_app
app = get_app('some_config_file.ini', 'myapp')
Where "myapp" refers to:
[pipeline:myapp]
pipeline = foo bar baz
http://docs.repoze.org/bfg/1.3/api/paster.html#repoze.bfg.paster.get_app
Then use whatever twisted has for serving up WSGI apps:
serve(app)

config = Configurator(package=some.package, ...)
... might be the right solution, depending on how you're calling it.
