A problem with "The other is to pay your host for a unique ip for each of your sites." is that most hosting companies want to know why you want a unique IP, and they do not easily give away IP's. It's not like, you can go and buy 30 IP's, no questions asked. The only case when it's not questioned is when you are buying a SSL certificate.
