"I can’t sell access to my Mac via any kind of screen sharing."

This one was interesting to me. I thought maybe macminicolo.net might fall foul of this, if they rented out a mac mini to you, but it looks like they instead make you straight-up purchase a mac mini. http://www.macminicolo.net/jvmx_secure_signup.html

I wonder if this term/condition was in previous OSX releases and that's why they went this way, or whether it was a happy accident that they went with users purchasing a mac rather than renting one.
