Ivan, all, Mike Bridgen has elaborated on this in the comments to the post.
I am copying his comments here: --- pubsubhubbub (0.1, anyway) doesn’t chain together in the way you’ve illustrated, because it’s not symmetrical — hubs don’t get subscribed to other hubs (or indeed, subscribe themselves). While you wouldn’t have to change the protocol, you would have to change the idea of what a hub is. But I guess you are setting out to do that anyway. For processing I can subscribe the remote processing service to the hub, and subscribe myself to the remote processor. Taking into account the verification, it would probably go 1. Me -> Remote: Please give me a token for this hub to post to you 2. Me -> Remote: Please subscribe me to you 3. Me -> Hub: Please subscribe Remote using this token This requires me and the remote processing service to understand some generalised bits of PSHB, but nothing extra of the hub (I don’t think). --- Cheers, alexis On Mon, Jan 11, 2010 at 5:21 PM, Alexis Richardson <[email protected]> wrote: > Ivan > > Possibly related to what Jeff says: how do you think hub-hub chaining works? > > Separately does PSHB subscription still work in your model? > > Great article btw. > > alexis > > > On Mon, Jan 11, 2010 at 5:14 PM, Jeff Lindsay <[email protected]> wrote: >> You should look into the greater webhooks ecosystem (slowly being called the >> Evented Web).
