It won't solve the spam problem either; in fact it'll just make the
spammer's job easier. Instead of wading through a load of spam messages,
recipients will have to wade through a load of spam message notifications.
Spammers will concentrate the important part of their advert into the
notification instead of the message, in the manner of bluetooth spam and
spim. They can just spew UDP which is much cheaper than SMTP and much
easier to forge. DNS blacklists would become useless.

The problem is not network bandwidth or disk space or CPU, the problem is
people's time. IM2000 optimises the former 3 at the expense of the latter.
