Is this entirely an open source project, or are there plans to do something like Keen.io?

Not so familiar with Keen IO. Looks like analytics-as-a-service for collecting and visualizing data. We're focused on helping developers build predictive features like recommendation, discovery, etc.

Yup. We're definitely committed to open source. Source is all up on GitHub https://github.com/predictionio
