Oswego0522, would a wifi network be feasible for you?
The others on this forum will doubtless know more about this technology than I, but we use an Apple Airport Extreme router ($179US) and extend the range with an Airport Express ($99US), so my wife can use her iPad throughout the house. Since you're not streaming, this should provide enough bandwidth. While ours is a Mac system, these devices will also work with PCs. (I'm also running Cat 6 cable in-wall from our router to our audio system, as it seems most audio/video gear uses networks these days and a gigabit network should provide enough speed for our needs.)
I would, however, use a wired network for firmware updates, as you don't want a hiccup. If it's feasible, perhaps for such updates, you could use a long ethernet cable for the few minutes needed to update, or simply remove your BDP2 from the system for a short while and move it to a location nearby your main network connections.
You should very much enjoy the BDP2 and BDA2. We received ours, and an SP3, this week, and the sound is superb.
