Today I rolled out public upload URLs to Pipefile. One of the major complaints that I received from prospective customers was the friction required to sign in and send out file requests each time you wanted to receive a secure document. Now you can set up your own shareable public URL (ie. pipefile.com/yourname). Upload your PGP public encryption key to the site and select your username. When others visit your public URL, we'll encrypt any files they add to the upload form with your public key before sending them to our servers. You can then download the encrypted files locally with GnuPG, GPGTools, etc.
