I have several sites on a short range of IPs, many on the same IP, all on the same server. I have links from my company site to them all and some of them link to each other. Never had a problem yet, though whether google treats the links or just ignores them, who knows?
I do know that almost as soon as I upload a new site and update my online list, the SEs come buzzing around.
I link for my customers' and their customers' convenience, not for google's. Which is what they told us to do, isn't it? Build sites for customers? Or was that last week's latest advice?
