I started now with Pubsubhubbub (and all about realtime things), but I having trouble with the Subscriber option.I'm trying to develop a webapp in PHP to:[*]Subscribe a RSS (previously Published) to the Hub (http://pubsubhubbub.appspot.com/);[*]Read notifications (updates) from the Hub for the subscription;without succeed!!! 
I verify that exist a library in php to the Subscriber (in Git), butusing this lib can't make the Subscribe work's (get a 409 error!).Is there anyone who has joined all the pieces and want share withother users?Can post the source code for the Subscriber and the Management ofupdates from the Hub ?Is a great help for the newbies in this "realtime" things.Regards,DDLuis
