Hi, Now, a subscriber client implemented in Java can be fetched from: http://code.google.com/p/pubsubhubbub-java/
The code has been tested by me but it would be cool if some of you can test it too and provide us with some feedback. We're interested to check the code in the main repo of the PubSubHubBub some day too. Regarding the publication client part of the code, Royans has been worked on that part too. Thanks, Cheers, O.
