I did the same search, and was pleased to see my post is the #4 result. What's even more interesting is that Whitehall Lane (and Kim) are the focus of this small-business profile from Apple (PDF), which gives some insight into the technology underpinnings of a small winery. Worth a read.
The Apple case study also hints at a new venture from the Leonardini family: Leonardini Family Winery (www.leonardinifamilywinery.com doesn't have anything on it yet, although it is registered to Whitehall Lane). What's up, Kim?
