Safestrap. Remember, the main reason for Knox is so that when you leave the company, they can wipe out all company data without wiping out your personal stuff. With Safestrap you dual-boot. One slot for company stuff, one for personal stuff. Boot as needed. When you leave, they delete the company slot. (And Hashcode gets the money he deserves for coming up with it, so maybe he can take time off and keep it updated.)
