Google treats internal links from one site (almost) the same way as external links, so I don't think it hurts to tell G that they both belong to the same person.
I have all my sites under one account.

Most of my sites rank very well, maybe it even helps the other (i.e. new) sites to inherit trust from the already established ones.

edit: @trinorthlighting: maybe I should read _all_ posts before writing my own :)
