I think Airplay mirroring can do all that stuff too.
Not that I am aware of. iTunes can send to multiple Airplay locations, but I don't know how you would do the same thing with other apps (like Spotify) without Airfoil.
From what I can tell, other than iTunes, you can only play audio on one speaker at a time. If I am missing something let me know. I am not an expert on OSX. The main reason I mainly use Macs at home is because I work on Windows all day and like the change of pace.
