First, a compliment to Raf: RemoterVNC and RemoterFusion are just excellent. I use them all the time, and I am so pleased with how well they work.
And a question: has anyone figured out how to sleep a Macbook screen without putting the computer to sleep? The usual keyboard shortcut (shift-control-eject) does not seem to work with Remoter. I use this when accessing a Mac at work that I want to leave running yet screen-locked to foil any casual unauthorized access. Thanks for any suggestions!
