I can see a huge potential in the consulting market. Many web developers/designers manage a large number of domains for their clients and they obviously want to maximize the productivity for domain-related tasks.

In the near future, we will launch our APIs as well as a white-label platform for these needs.

Your virtualmin idea is great. Yes, with APIs everything can be integrated and centrally managed.

EDIT: We're definitely interested in offering bulk discounts, email your needs to support@nameterrific.com and let's see how we can work together.
