Well, I finally had time to figure out how to configure SAB, SB, & CP installed on my Revo 3610. They download to a Unraid share via Cat5e LAN, and I am happy to say that:
even while heavy fetching, downloading, verifying, unpacking, renaming, moving, and notifying XBMC are happening simultaneously, 720p BluRay mkv files still stream flawlessly from the Unraid share to the Revo, through my Yamaha receiver, to my HDTV. This little Revo never ceases to amaze me.
Also, I installed the Aeon Nox skin. It's beautiful, and menu transitions are WAY quicker than they were with Aeon MQ2. I feel like I just opened a a new toy on Christmas!
I don't remember exactly where I saw someone else asking if the Revo was capable of this, so I just found this old thread...
