 * Hi Matthias!
    Thanks for your diligent work on this plugin over the years. I 
   have a unique situation insofar that I have multiple domain names with multiple
   hubs (one for each domain name), pointing to the same set of server files/database.
   This is NOT a WP Network site; its an über custom WP cluster of domains. All 
   sites have their own feed and the WP feed gets redirected to their respective
   feed URL, but I do not wish the separate hubs to appear on all feeds, only their
   own hub. The feeds are all on separate subdomains, i.e., feed.domain1.com, feed.
   domain2.com, etc. I have root control of both the main server and the feed server.
   So what appears in the XML is: `...<atom10:link xmlns:atom10="http://www.w3.org/
   2005/Atom" rel="hub" href="http://feed1.superfeedr.com/" /><atom10:link xmlns:
   atom10="http://www.w3.org/2005/Atom" rel="hub" href="http://feed2.superfeedr.
   com/" /><atom10:link xmlns:atom10="http://www.w3.org/2005/Atom" rel="hub" href
   ="http://feed3.superfeedr.com/" /><atom10:link xmlns:atom10="http://www.w3.org/
   2005/Atom" rel="hub" href="http://feed4.superfeedr.com/" /><atom10:link xmlns:
   atom10="http://www.w3.org/2005/Atom" rel="hub" href="http://feed5.superfeedr.
   com/" /><atom10:link xmlns:atom10="http://www.w3.org/2005/Atom" rel="hub" href
   ="http://feed6.superfeedr.com/" />` I will attempt to fiddle with the WP feed
   filter, but I think that may not work, even with adjusting the priorities. I’ve
   gone through your code, and I don’t see any filters/hooks, but maybe I missed
   something. I can probably filter it out on the feed server, but I’d rather filter
   it out before it gets there. The domains all run the same instance of WP, just
   language-filtered, so I need all the hubs pinged simultaneously when a post is
   created. Thanks so much!
