I have been troubleshooting my Mom's computer problems at a distance and I'd like to know what options there are for remote screen sharing. I know Skype and iChat have options for that. What other applications are there that do this? I know MobileMe/iCloud has the "Back to My Mac" feature, but I'm assuming that's for controlling another personal Mac of yours that setup with your MobileMe/iCloud account. Any suggestions or feedback is appreciated. Thank you!
