+% Sending...
+%
+%  0. Sender opens GajuExpress interface
+%  1. GajuDesk asks GajuExpress for a price quote
+%  2. GajuExpress responds with a price quote: pucks per byte per height
+%  3. The user inputs the public key/ID of the party the data should be sent to
+%  4. The user picks the file or directory to send
+%  5. The user decides whether to sign the package or be anonymous
+%  6. The user picks which key to sign with if not anonymous
+%  7. The price is shown
+%  8. The user agrees or aborts
+%  9. If the user agrees, a payment window opens and they send a payment to GajuExpress
+% 10. Once GajuExpress verifies the payment, the upload begins
+%
+%
+% Receiving...
+%
+% 1. Sender opens GajuExpress interface
+% 2. GajuDesk asks GajuExpress whether there are any packages waiting for KeyList
+% 3. If yes, then the pending deliveries are shown in the delivery panel
+% 4. The user selects + clicks open (or double clicks) a package
+% 5. User selects where to unpack it in a file dialog
+% 6. GajuDesk downloads the package from GajuExpress
+% 7. Progress bar
+% 8. File is decrypted and optionally signature verified
+% 9. GajuExpress deletes their copy of the file
