It would be kind of nice to have something like mobile hyphanet.
I've mostly refused to host anything like an open SMB share for family for fear of being liable for whatever the hell they might decide to put in it (or just getting my door kicked in or whatever, regardless of lack of responsibility as has happened with Tor node operators; acab).
Having something where I can provide storage without being able to see would've handled that.
This is indeed a way of asking if you know of anything like that, chat.
