Add tor/onion service capability

[too-ugly-for-tv]

It would be so cool to run a local onion service to access my camera web interface over a .onion address via tor browser. Has it been considered?

It's open source and very well studied, as well as incorporated into many other projects.

I know I can run a tor service on RaspiPi or other compatible host and reach out to the cameras that way, but I'd love to take the Pi out of the solution.

This would allow use though NAT or filters outside your control like phone data carriers since tor is a highly robust protocol meant for hostile environments/governments/corps. Security/trust is debatable as much as any other service, but it's so simple to configure and it just works.
