Perfect! Sometimes I need to send a dropbox link from one of my devices to a computer at work to print and stuff. Until now I have always used email or facebook, but because I use long passphrases and a key manager logging in on the other computer is always a hassle. This will serve that use perfectly - use a random passphrase and then paste the link, type in on other computer and then open it from there. Great!

I would love to set an expiry date for this use case though as I only need the link for one minute to retrieve the files.
