RSS or Atom Feed from a HUB

Hi there,

I have a question. I am looking to use this Plugin and the project I am working on will be pulling in articles from a Hub which uses the Google Pubsubhubbub protocol which basically just means it will PUSH content to the RSS feed instead of the RSS Feed having to be polling from the blog itself but goes to the Hub.
I still have to look at the feed itself but the way that Google Pubsubhubbub works is that it seems to add a <link> tag in the RSS or Atom feed that has a rel=”hub” and rss readers that are compatible with it I.E feedburner and Google Reader they recognise the link attribute and will go to the hub to get their feed instead of the blog itself.

Can I use this plugin and does it work with that sort of service (PUSH, pubsubhubbub)?

Thanks
