A discussion about distributed federated systems else-network did bring up some concerning history that we should keep in mind:
#XMPP was, briefly, the dominant messaging system on the Internet. It was fully federated allowing hosting anywhere. Major extensions were being done by major companies (Apple adding voice and video for example). And it all fell apart because the three big providers (Apple, Google, Facebook) ditched it to have more control.
