@akkartik @neauoire @inscript I want to build a federation of Betulae and Mycorrhizae, so they can interlink and transclude each others' content.

For example, I have a category named Cats on my Betula. And you do, but it's named Felines. On my Betula, I say: “Hey, there's this page out there which also has cats! Federate with it!”. Then my Betula GETs your Felines, parses it, and shows them nearby my Cats. Data updated once a day.
