For example, I just had an issue where I needed to transfer a very large file between two devices on different operation systems and shitty WiFi, and I was like "I'm sure there's a tool for that, maybe zap.store has it listed." And sure enough, LocalSend pops up and it just worked like a charm. FOSS, signed, verified, trusted. Like it should be.

 so I can stop send myself gpg encrypted mails I think..  

 Localsend is godsend. It's faster than AirDrop and works cross platform. Plus it's FOSS! 

 @franzap new commercialization avenue: FOSS merch store. First hat/tshirt I will buy is localsend

 Yup, on my list! :Check:  

 Another good one is Wormhole William, you can use any other Magic Wormhole client on the other device/OS
