We also have our dashboard that competely manages all of your domains from one spot. You can install new domains, check individual or overall traffic stats, set options, edit templates all without touching any files or manually editing an individual domain. On top of that we actually build in several link spamming tools such as a built in blog ping system, built in trackback spam system, and a recently added .edu spam tool. All automated and all completely integrated into the software. I haven't seen anything similar on the market, especially at this price point.
