[pubsubhubbub] Simple Python Subscriber Client

[Dave]

I've tried writing a simple python client that doesn't require the
appengine sdk. It runs for around 90 seconds saving the buzz firehose
to a file and then stops.

https://pubsubhubbub.appspot.com/ then displays:

Delivery to domain:     BLOCKED
Delivery short-term:    100% errors

Does anyone have any ideas on how to fix this, or a working python
client that isn't built on appengine?

Thanks
