Hi (i posted this in software forum, but not much response) My Mom just got a new mac mini and we are trying to get share audio and share screen to work. 1. If I take my mac mini to her house, and plug it into her modem/router (it's a modem with four ethernet ports), is this "the same" as if we were communicating via internet miles away? If not, is it still useful for getting the share audio/screen to work? 2. We used to share audio/screen via ichat, now it's via imessage, right? THANKS!
