I remember thinking about this on an app I was building about 4 years ago. At the time, I was thinking that having the logo at the bottom would be a bit of a differentiator, and might make it recognizable, as many people I figure just ignore the top-bar logo area. However, The topbar is often used for so much other stuff that users are looking for like search and navigation links, that moving the logo to the bottom (you may have a different idea) ended up just taking more pixels and in my general opinion asking (no a/b testing), most people just didn't like it as much as the stock standard, top left position. I seem to recall a few sites I've seen use top right positioning for the logo, but nothing is coming to mind right now.
