Lets imaghine you are on a server sharing an ip address with another site. The other site starts doing all sorts of thing and lands it's self in trouble with google because of their techniches.
Google may take action against the ip and this could effect your site.

There are many 1000's if not 1,000,000's of sites using shared IP addresses with out any problem.
Another thought is that if Google did start to ban by IP all the cowboys would do is change the IP address - it's much easier than changing the domain which is what they have to do at the moment.
