An idea I'm thinking about is to make it so you could have a Tiddlyhost site also serve a version of itself on the equivalent (or maybe a different) Tiddlyspot url. That way you could migrate to the Tiddlyhost style authentication and saving, but still have old urls work.
Or, maybe there could be an option to "upgrade" or "migrate" a Tiddlyspot site to a Tiddlyhost style site, but keep it hosted on its original tiddlyspot.com subdomain.
Probably won't be possible for Tiddlyspot sites with dots in their names unless, since the SSL won't work for those. Could maybe replace the '.' chars with a '-' for those.
