Thanks, André.
Why I'm doing this. It is the only way to buy some legal product for my server. Standard version is not very cheap, you know. The Essentials version is suitable for me, but those limitations... not more than 3servers up to 2 sockets.
For my 1server * 4sockets it will be about 10 times more expensive.
Why do you say "never for production" - is it a legal point of VMware?
Then, I think, if you buy some soft, it must be much more reliable... Isn't it 
2 questions are answered so - it's possible and legal.
