Well the hemp milk did curdle, but it was obviously way too diluted and low-protein. I wound up with literally half a jar of whey, and the other half very, very loose yogurt, really more liquid.

Don't think I'll try that again. Maybe I'll try again with Hemp Bliss. But really, of soy beverages, only unsweetened Edensoy (12 g protein per serving) is rich enough to make decent yogurt. So I'm not getting my hopes up for Hemp Bliss. If I can get my hands on some hemp seeds I'll definitely try making my own, though. The main reason making soy milk is such a PITA is having to grind it hot; other nut/seed beverages aren't so bad.
