No, it's not the electron engine so any similarity is probably some of the same things need to be done in both engines. DOS and DC for that matter are running in our own new engine (so not Gamebryo either)
As far as multiplayer is concerned, right now it's 4 players, but the server architecture is such that that can be extended. We'l see how the editor gets picked up by players and if there's demand for more players.
