screensharing with VoiceOver

Hello All, I have a totally blind friend who just got a MacBook Air about 2 days ago. I'm trying to help him set up a few basic things (like telling VoiceOver to come on at the log in screen, etc.) and he is having trouble pressing the right key commands, etc. so it's becoming increasingly difficult to accomplish things by trying to tell him what to do. It would be much easier if I could simply control his mac. I know Apple has screen sharing, and the ability for ssh, but I didn't know if VoiceOver was compatible with either sharing method. I know you can screenshare with Skype, but Skype doesn't allow you to control the other person's machine. Has anyone had experience with this before? I also thought about using something called Join Me, but I wasn't sure how compatible that was either. I'm trying to find a solution that works, before I spend the amount of time trying to get his computer to give me the information I need to connect to it using whatever sharing service I'll end up using. He has a bit of a learning disability, so certain things, like controlling computers, are a little harder for him then most of us. Any help would be greatly appreciated. Thnk you so much! Rocco
