I have an idea for a community of sites of related content, (think wordpress mu but all blogs are related in some way) all being hosted on the same (or small network of) dedicated server/s with limited dedicated ips. All sites would be related and would normally benefit from links from each other. Actually, a major key to success will be the link love that will flow naturally in this community. Will Google ignore the links because they are coming from the same ip? Is that considered at all? Just curious.
