This is definitely a valid concern that we should have addressed a long time ago but as me and TA were always for the good of this project we never signed a contract in good faith. In fact our intention is right the opposite. We are discussing to use a later version of the engine (engine5, what a surprise :P) for the emu as well, that could enable core3 to support way more concurrent players on multiple nodes. Anyways, an unlimited lifetime license should be granted on paper so i will get to the lawyers about it.
I'm not allowed to share any project names where it is being used, but one could easily find information looking at the right places..
