This is something I wanted for myself so I can more easily maintain and update my two MPTW5 templates. I figure it could be useful for anyone who wants to use Tiddlyhost as a place to publish and share a TiddlyWiki that is built or maintained elsewhere, e.g. plugin or template authors.
It’s similar in style to the existing thost-downloader script, but this one supports uploads. See thost-uploader.
I wrote some notes about how to use it here.
