I don't quite see why this is only a problem with "unregistered users", 
by which I guess you mean people from your own company who haven't 
logged in?

People who have logged in will be able to do the same.

Note that ZendTo does log the IP address a drop-off came from, so you 
would be able to see who had done it by looking through your logs.

Why doesn't the user just copy it onto a USB stick that they have in 
their pocket? Surely that's simpler? Or upload it to any of the various 
free cloud storage services there are (such as Dropbox, Evernote, 
iCloud, SkyDrive, etc etc)?
