I fear you misunderstand the case law, SPN. The situation I describe above (a California resident, in Texas, engaging in a transaction legal under Texas law with a Texas resident) creates no avenue for jurisdiction for a California court. Indeed, Shoe makes clear that a "one-off" transaction (such as an individual-to-individual sale) would clearly fail the "minimum contact" standard in the case and would be a violation of the 14th Amendment. (Specifically on Internet cases, Weber says: "the likelihood that personal jurisdiction can be constitutionally exercised is directly proportionate to the nature and quality of commercial activity that an entity conducts over the Internet"). In addition, in Aschi, the plurality opinion holds that "merely placing goods in the "stream of commerce" [is] not enough to establish personal jurisdiction over the party responsible for placing the goods."
