That's a very common layout as well. I have been using the same style ergonomic keyboard for the past 6 years so the UIOJL that I use is spaced out pretty far from the WASD, achieving a similar position to Dave's layout. And also, the ergo has the Insert, Home, etc buttons rotated 90 degrees and half sized.
Now I play on my laptop more than anything and its been interesting getting used to my hands being so close together but its actually not bad and considering how much and how quickly I type, it ends up feeling pretty natural.
