The UI for this shouldn't be too difficult - you will need to subclass
Request::Respond, so that instead of sending the document it sends a
link with a secret.

To work with HTML documents you will need to set a cookie (via a
redirecting CGI script) and use that cookie to grant access in
"can_user_view_document"/"can_request_view_document".
