I would like to open a question about VMware Essentials Kits licensing but, searching through the community I've found this: http://serverfault.com/questions/215405/can-you-help-me-with-my-software-licensing-issue

Which lead me to confusion, if it's offtopic or not to open those kind of questions in Serverfault.

I think, that's too vague to limit all the licensing question to just this one, there are a lot of specific cases that would be discussable.
