Magnum, you summed it up very well. Exactly the problem we encountered.
Actually, I've just read the Licence Agreement (which is, for once, not too long and understandable!), and here's what I found:
2. License
Vienna Symphonic Library GmbH grants to You, the Licensee, a non-exclusive, perpetual license to use the Software for your own personal use and not for sublicense, subject to the terms and conditions stated in this License Agreement. You may: (a) install the Software on one or more computers, (b) transfer the Software from one computer to another provided that it is used only by the licensee ...;
3. Restrictions
Unless expressly permitted by this License or otherwise applicable law, You may not, or allow any third party to, ... (b) install or electronically transfer Sounds of the Software on a network for use by multiple users, unless each user has purchased a license; ... .
So, let's say you split your Woodwinds I and II between two computers, to have Flutes and Oboes on Slave 1, and Clarinets and Bassoons on Slave 2.
It is authorized by the Licence Agreement to "install the software on one or more computers", "providing that it is used by the licencee" and "not by multiple users".
So, you put the software on two computers - but you still use the two licences - and you only have one user.
The only thing is that you can only have one ViennaKey to do this - since some of the WWI and WWII are both on each slaves - but you do have the two licences on the key.
So, in that specific case, you could plug the key on one slave, boot it up, remove the key, plug it on the other slave, and boot it up too.
This would only works because these are slaves - you never access the GUI, so VI won't be looking for the key once it's loaded. You would still need the key when the computer crashes, when you restart on purpose, when you do updates, or when you need to access the GUI. So, you couldn't "launch the whole thing" and then get rid of the key - you do need it (no fear of keys being given away to someone else.)
As such, this wouldn't work in a situation where you access the GUI on a daily basis. Which is fine, because, in that case, you don't need to have more than one ViennaKey anyway, since you're not spreading your samples over various computers. This would only be valid for a slave/farm situation.
Anyway, it seems to me that this is allowed by the Licence Agreeement. Did I miss something or am I right on this one?
