alt Hacker NewsThat requires having an account on the other machine. What's missing is anonymous scp, where the other side just opens up a directory, and you can copy into it. One can build something like this with rsyncd, but it's not a pretty shell one-liner to get it going and it still requires both devices to be on the same network.
What I responded to was "wirelessly transferring files between a phone and a computer", assuming that I am the user at both ends of the transfer.
If I want to share something with someone else, there's a "File Sharing" section in phone's settings that enables anonymous WebDAV sharing, and it works fine too. There's Bluetooth OBEX too, but that one's fiddly.
