I'm not exactly sure I understand this. If the browser shows it in the 
address bar, then users will copy it, and use it on other occasions. 
Also, web developers will copy it and use it. Of course, most of that 
would be accidental, not on purpose.

On the other hand, I can't see much use in using it on purpose. Surely, 
no web site in their right mind would want to use it, because it 
essentially says "we are secure, but don't really think we need to be". 
Intranet applications wouldn't need to use it either, because for their 
own stuff, companies have easier ways to verify that there are no 
viruses,... around.

So all in all, an URI scheme doesn't seem to fit here. To me, it seems 
more like a case for a separate indication in the browser (a lock with a 
different color or a half-broken lock or some such, better ideas welcome).

Regards,   Martin.
