@chris_martin @argumatronic @acowley I was thinking the other day about how to proxy your identity through your own Webfinger instance that redirects to a real Mastodon server. It would function like an MX record for email. The only thing missing is: PubSubHubbub doesn't have a way to transfer subscribers from one hub to another. Solve that problem, though, and you'd just need an HTTP server to proxy your (portable) Mastodon identity.
