SRC Open Sources their Geocoder

Read over at DirectionsMag that SRC has chosen to open source their Explorer geocoding product. I love the idea of putting more tools out their in the open source arena, especially in the area of geocoding. But remember its all about that data, and these days its seems like getting data coverage is the hardest part.

So assuming you take your open source geocoding software and some free TIGER data, you are set to start geocoding on a mass scale. Does anyone have feedback on just how good TIGER is these days?
