Call me silly but if you don't need a host then why do you need a link? That does this do that .html can't?
Telling a normal person to click that link (or, go to decoder.com and paste this text into there, for a more distributed version) is much easier than getting them to view the HTML.
I still think this is really interesting though.
Think about the tools a modern political campaign uses, it would be somewhat similar.
But aren't there any other encoding standards? Perhaps also with encryption?
I'm not knocking this url idea. Simply what-if'ing other possibilities.
