This is very cool.

In case you missed it PubSubHubbub is a way for you to receive near-instant notifications of change updates to a PubSubHubbub enabled RSS/Atom feed. So, the moment a new post appears on a blog for example, you’ll receive instant notifications in PubSubHubHub supported applications (eg. lazyfeed.com).

When XMPP support in Google App Engine was announced, Coder Mihai Parparita, took it upon himself to create PubSubHubbub-to-XMPP bridge making it possible to receive real time updates of PubSubHubbub enabled feeds via XMPP (eg. GTalk).

After a few stumbling blocks, Parparita managed to cook up a pretty nifty application that will essentially let you receive an update in GTalk the moment a PubSubHubbub enabled feed has been updated.

It’s not too basic either, no need to find the RSS feeds for each URL, PuSH bot will do that for you. OPML import for bulk subscribing is also enabled so no need to add each URL one at a time.

If you’re a big IM user, PuSH Bot might just slot in neatly into your work flow.
