I can only support the wish for a single multiplayer experience. It's a very bad decision to divide the mulitplayer into two groups, I haven't heard of any game that did that before.
I know that it's probably the easiest way for Larian to use Steamworks for multiplayer. But if it doesn't work with all versions on the market they should come up with another solution or at least an alternative solution.
Wasn't there some kind of "virtual LAN" in planning? So that you can play multiplayer with everyone having the game no matter on which platform? I would like to know more on that topic....
