I am thinking about making my iMac (bedroom) my iTunes db. I have my MacMini Server in the lounge that i play all my movies etc. Just interested in thoughts of pos/neg of having just the one iTunes to edit/upkeep... Does iTunes need to be open on my iMac (like when sharing) for the MM to use and play? Will everything perform the same? Artwork? voice or stream lag? Any chance (or hope) of multi room play? eg. play same song on both at the same time? Is home sharing worth looking at?
