I also hear that Front Row doesn't allow you to listen to music from another Mac sharing that music. Similarly photos. And that network aliases aren't followed for movies. So you need to have all your music, all your photos, all your movies, on the Mac mini in order to access them.

Pretty disappointing. Front Row isn't quite a media centre - just a pretty player for a couple of apps running on your machine. Also appears to have no plug-in architecture, so no EyeTV plugin for recording/watching digital TV or recorded TV, no radio shark plugin for radio, not even a dashboard plugin so you could see the weather, read a news headline or look at a TV schedule.
