So SEO hosting is basically hosting that has all/some of the common server side optimizations already done off the shelf. Maybe a better name would be SE Friendly hosting or SEO'd Hosting.
Alot of the optimizations can be done by .htaccess but an important one has to be offered by the hosting company which is a site specific ip address. This allows your site to be seen independently from other sites on a server.
If there's two sites on the same ip address and one is constanly using blackhat techniques then SE's will view all sites that are theme related at that ip address as offenders. Of course there's exceptions to the rule but that's the rule of thumb. With your own ip address your site is judged by itself.
