Fair point and makes sense. If you publish the rank along with the data itself that would be very useful. Perhaps having a few sets of data? 3 million top pages, 3 million deep pages etc...

Personally I would like to see around 20-100 million pages or whatever is about 500-1000GB. That's enough data to work with on a local machine and serve up some meaningful results assuming you want to build a search engine or just do some deep analysis of the web.
