Shoutbox

But then again, there are secuirity issues for silent communication. For instance, there are adware and spyware out there which hide a certian string sent by messenger, like "Your friend has a new buddy icon etc. etc. etc.". So it would be perfectly possible to send links without the users permission.

Also, silent communication would only work if the other person had the script, and there is no way of finding out if the user has the script without some kind of central databases of the email addresses.
