Existing pubsubhubbub ajax proxy/bridge? (Like Google Feeds API v2 with Push)

I'm looking for a server side component, preferably java, that will allow me to subscribe to pubsubhubbub feeds through javascript. I understand that subscribers are server side applications in the standard rest/pubsubhubbub format, but Google seems to have created a ajax bridge that looks quite handy.

Unfortunately, I'm dealing with data that simply cannot leave our servers, let alone go through Google's.

Is anyone aware of a (preferably free) server side proxy for pseudo javascript pubsubhubbub subscribers?

I know for a fact that Kwwika and Pusherapp are working on this. I can intro you with these guys if you want.

If not, I believe this should be relatively easy to build with stuff like Node.JS for example. This code on Github should be a good first start. Things like this have been built with it.

We (superfeedr) are trying to get more people building similar things...

You can see an example using a combination of Superfeedr and Kwwika within a web application that lets you subscribe to any RSS feed or track keywords within RSS feeds here: http://superfeedr.kwwika.com

And you can get the source code in GitHub here: http://github.com/kwwika/ASP.NET-MVC-PubSubHubbub-Subscriber/tree/Kwwika-Superfeedr-Demo

There is a java implementation]1 of the subscribe part available. But the hub-part hasn't yet been implemented in java which is needed to subscribe to the feed which should be private. For the javascript(jquery) part I would just use simple long-polling.

I don't think a free solution like that exists (yet). Even google's push API isn't open yet.

Unfortunately, I'm dealing with data that simply cannot leave our servers, let alone go through Google's.

There isn't yet an implementation of the HUB-part of the pubsubhubbub protoccol. But if it is internally I also don't think you need this kind of fan-out the hub(specification) is offering(broadcast to other servers).

I think you could just use A comet framework like Atmosphere to suspend connection and broadcast feed diff. I think this can be written quick with the Atmosphere framework(1 day you will have a working prototype).
