Actually, many professional applications have multiple installations/single operator licenses, which I think is fair and it's all I ask. In fact, nearly every graphics, 3D, compositing, and music program we use in our studio makes this allowance. The one significant exception, as mentioned earlier, is Toon Boom, which does allow you to occasionally move your license but their system can at times be very inconvenient, like when I'm busy working at home and at a client's location on the same project. Once, for example, I arrived at the studio only to find that my license was still active at my home location, so I had to run back home to deactivate it, and then return to work. And the system can be nightmarish when it locks you out on a weekend with a deadline looming, and there's nobody available in tech support to reactivate your license. Again, love the software, hate the licensing. (Sadly, I was told that they rarely get complaints about it from other users, so I don't think it's likely to change any time soon.)
You mentioned Adobe CC, which allows two active installations per license with single suser privileges. I think this has been ideal for most freelancing artists. Many (most?) freelancers have a workstation at home and a mobile computer for working off-site, and it is necessary to be able to run the software on two computers, even if they only do it occasionally. Thankfully Adobe recognizes this situation, and they even went a step further by allowing users to deactivate their licenses remotely when it becomes necessary--like in the 'Toon Boom' situation I described above.
As it turns out, Anime Studio 10 allows for multiple installation/single user, so it's all good by me. My concern this morning was that they had gone with the 'Toon Boom' model or, even worse, node locked it forever to a single computer.
I'm soooo glad this isn't the case.
