Thomass - let me describe my scenario in a little more detail and see if what you're proposing relates to that. I'm saying that Person X is on their computer, goes to a web site containing a form. The form asks for Person X's kindle email (e.g.
PersonX@kindle.com) which can be used to send documents to their kindle. The web site also tells the person to add an address to their kindle whitelist (so that they can receive emails with attachments from that address.)
From your comments above it sounds like you're suggesting using the Kindle to navigate to the web site and from there clicking a link and download the file directly onto the Kindle. That's interesting and informative, but is the first scenario also possible?
Thanks,
Wil
