I don’t have a strong or thorough understanding of security issues in the back-end (other than Single-Sign On), but you had me at biometrics. I am sick of the current solution with millions of usernames and passwords we can no longer remember. Most of our secure information is commonly known we use it so often. From what I see in your presentation, there would not really be confidential information, just use of learning spaces. YOu are addressing many of the challenges but I believe they can, and need, to be overcome. This is my favorite Venture, Victoria!
