Rather than go through self-publishing, you can use the personal documents service to upload a short document and send it down to the device. Details are at http://www.amazon.com/gp/help/customer/display.html/ref=hp_p.... There are fees if the user isn't on WiFi though...

That is... inspired.

It doesn't matter how little time I have on my hands, I really want to do that now. Or maybe an app that lets them live chat me?

This is brilliant. I would totally do that in a heartbeat. I don't know if I would have them buy it (although that might be necessary to get them to read it). You could presumably do the same thing with an app which ran and said, "Let's figure out what your real email address is shall we?"

Oh, I so much I could upvote multiple times. Brilliant.
