Hmm. The Mumble panel just tells me "Online" and nothing more. Is it supposed
to say more stuff, like the onion address?

I think that's acceptable.

Hmm, there seem to be some Python modules on github that do this sort of thing:
     https://github.com/redacted/XKCD-password-generator
     https://github.com/beala/xkcd-password


However, your "random characters" approach should be fine for now since you
assume that your users will copy-paste it around. Adding more password patterns
can be a task for the future.
