I've been thinking a lot about this case specifically. And you are right, phones are largely not supported right now - I've been researching how to make that happen. One case I've found that works for me currently is running connet via Termux - and I've made the necessary changes to support that.

Native iOS/Android clients, if possible, will probably be the next things I'll work on. At minimum they should enable you to run a "source" (e.g. a consumer of an exposed service), but ideally it will be the whole deal.
