I can't believe that there isn't a simple service to transfer data between my cellphone and my computer without going through the internet. iTunes is terribly bloated, MTP is a mess, and Bluetooth is slow and frustrating. Back in my hacker day I used to have an SSH server open on my cellphone and use it to transfer files back and forth with my computer. Why isn't there a mainstream service like that?
Works great, and I'm planning on integrating that functionality into my project which transfers files between laptops using only wireless cards, no LAN required. https://github.com/spieglt/flyingcarpet
