I use SE in a little planetarium under wine/Linux, Steam dont be usefull for us
From my understanding Valve recently added a heavily upgraded version of Wine to Steam that manages to run a lot of Windows games, so SE might actually be able to run better than before under Linux if it uses Steam. Read this
