Scaling to Hundreds of Billions of Triples

Nova Spivack Talks with Talis (in MP3 format) talks about the recent work by Radar Networks and how they require a triple store to scale to hundreds of billions (from about 45 minutes in). Mentions an interesting business opportunity (48 minutes in) to build a scalable triple store (mentions Tucana and Kowari and how it disappeared) that handles lots of writes and federated queries.
