Yes, it is, but I was referring to the clean separation that I mentioned before.
Right now it's a monolithic VOS, possibly even an ancient-style one.

In Erlangish, would we call it a node? It's an interesting idea to somehow give
nodes different rights, even if it goes somewhat against the transparency
property of Erlang distribution.
