I don't really understand what you're asking, but... If you're worried about Google deciding to suspend service, the easiest solution is to use Google Apps for Domains, which costs you a domain registration (~$10/yr at lots of places; search HN or the web for recommendations). If Google ever decides to boot you, move your domain - you can keep the same e-mail address. Be sure to keep backups of your mail; I like offlineimap, which is also useful if you e.g. occasionally want to mail from the train.
