Premium Install for VirtualMin Service

I was considering purchasing virtualmin and purchasing the install service. I am currently using Plesk 7.5 with a hosting provider and I am looking to migrate to my own servers running virtualmin.

Question, does virtualmin support custom nameservers like Plesk and the other control panels? Can I run all this on one server with two NIC cards and two external IP addresses for ns1. and ns2?

Also, can anybody else think about what I may or may not be missing when going from Plesk 7.5 to Virtualmin?

I am very excited about the commercial product and support.
Excited to hear your response.
