The license states that you are allowed to use vShare on one domain per purchase. If you do not want to violate the license, you will need to purchase one license for each domain that you run vShare on.

The whole "multiserver" thing is not the same as running vShare on two different sites. Rather, what that means is that you can have multiple physical servers hosting video for a single site. So, for example, large sites may have 2 or more physical servers hosting the videos for their single video site, which is allowed under the license. What isn't allowed is for you to setup two separate sites with only one license.

Physical example --> 3 Servers for www.example.com requires one license. 3 servers for www.example.com, www.example2.com, and www.example3.com requires 3 licenses.
