[fw-general] Feeds

[Daniel Latter]

Hi all,

I'm processing feeds with Zend_Feed and I am wondering how to get  
instant feed updates like Google reader?

For example, I consume a feed from bbc.co.uk and get a pubDate for  
each item, but if I look in Google reader at same feed I can see that  
it has been/gets updated almost instantly with new items? But the  
propoagtion to the feed takes much longer?

Now I know about the pubsubhubbub class that ZF provides that enables  
"real time web" but that is still relatively new.

So I guess my question is how can I architect real time feed updates  
like Google Reader.?

Thanks
Dan
