Hey, We've had several of users in the past who were struggling with making Subscriptions request from the server, for different reasons. I'm also trying to build an app with couchapps and they do not support making http calls from the server side. Finally, I know that a lot of PubSubHubbub requests are actually initiated by client inputs... so we decided it would make sense to be able to perform the susbription requests from the browser!
Check out http://pubsubjubhub.appspot.com/ it's also on github, just in case our instance runs out of credits http://github.com/superfeedr/pubsubjubhub:D Enjoy, Ju
