I'm not using plugins, but I had the same requirement as you to  
explicitly create the app and then run it - because I need the freeze  
scripts to make a single application.

My solution looked something like:

# myapp.py

from twisted.scripts._twistd_unix import UnixApplicationRunner
# Of course, that's just because the app is unix only

class MyRunner(UnixApplicationRunner):
	def createOrGetApplication(self):
		# The stuff that's usually in a tac file
		application = # ...
		return application

def main():
	config = { # stuff pinched by dumping 'config' during a twistd run
	# Also do the ServerOptions thing here if necessary

if __name__ == '__main__'
