Miyamoto is a high-performance hub implementation of PubSubHubbub written with Twisted Python.
Currently the hub is stateless and subscriptions are lost when the process finished, so it's not really production ready. BUT that's the first thing to be added once tests are in place. ;)
Installing Miyamoto is a walk in the park:
sudo python setup.py install
You can run the tests to be sure everything is OK:
trial miyamoto
You can start Miyamoto with miyamoto -p 8123, which will launch a web server running on port 8123. The root path is the hub endpoint. There is a preliminary/debug interface if you browse to it.
