Isn't that the same argument we hear from teachers and administratorts at brick and mortar schools? When I took a couple online classes in college I had to physically report for testing. If cheating becomes such an issue I'm sure "regulators" can mandate testing be done at a center provided by the course administrator. These types of concerns can be addressed at much lower cost than how we do now. Students with no family support will fare the same in either case. Actually, some students may do better because they won't be burdened with the stigma of being one of those "smart" kids. That's an issue that has been around since I was in high school 40 years ago.
