I'm so excited about this, it's actually a little bit embarrassing.
I've got two geo-related projects that are half-finished -- both because I was dealing with poor / non-existent geographic data. I haven't had a chance to plug this new data into my code, but I can already tell it's vastly superior to any other free sources out there (OpenStreetMap may have more data, but it's not as conveniently packaged).

Unless the data is in one of the proprietary GIS formats, then you're in for a late night hellride. GDAL/OGR may be your friend, or may not.
It looks like a nice dataset, but only has center lines for rivers -- no polygon data.
