The user *will* accept because nobody read the message.

I have the same hobby ;-)

You can't compare the security model of desktop applications with
web content.

The user will turn this off and if it is not possible to turn it off
the user will not use it.
It is the same problem as with outlook. People click to executable

Favicon for normal isn't a script and there is max. ONE connection per HTML

With postURL it is possible to make asyncronous connections and drop the result.
You can send 50 (or more) requests/second to a cgi.
That's  new!!!!

It's more serverside programming and less client side programming.
