None of the OtherStuff has enough users to keep the nodes up (yet).

I'm hoping to get institutional customers that only need to maintain their own node-network, but the social feed is the strongest pan-network use case. We need that use case hopping to keep Internostr exchange up, so that the Intranostr npubs can use the external nodes to hop from one Intranostr to another, smoothly and without being conspicuous, and to occasionally join the Internostr conversations.

Otherwise, you end up disjointed islands and the value proposition melts. Communication networks should be noisy and busy.
