Data Access Application Block and Oracle

I read about the Data Application Block yesterday and was intrigued, although for the life of me I cannot remember where I read about it originally to pass along some credit. So I checked it out and it is very nice and all, but alas my project uses Oracle not SQL Server. Initially I thought about porting it to Oracle, but I figured that it has already been done. So I did a little Googling and voila!, Microsoft themselves had already done the work in the Nile 3.0 demo application. Sadly, it was in C# and my current project is using Oracle and VB.Net. So now I am back to porting.
