Looking for server code about pubsubhubbub

[maksverver]

I believe the example code was migrated to: https://github.com/pubsubhubbub

I don't think there was a reference implementation of a hub, though. (Do you have a link that shows what you are referring to?)

there is a wiki page with some still existing code repos https://github.com/pubsubhubbub/PubSubHubbub/wiki/Hubs

These 2 tutorials are about hub server setup but all the Google/GAE links are dead.

So what I really need is a private hub which also has polling capabilities. I read somewhere that the ref implementation has exactly this and the appspot hub has turned it off. I couldn't find polling in a 0.3/0.4 library from the hubs link @pfefferle has shared. So any pointers will be really helpful.
