I recently got an 11" Macbook Air. I also have a 27" iMac that is on 24/7. I have successfully enabled screen sharing, but the resolution is so high on my iMac that it's hard to see on my 11" when I'm screen sharing on it. I have read that you can do remote login with Lion where you log in as another user. But can you log in under a different screen resolution on the iMac while still leaving my main account running at full resolution? Also, I'm running Parallels on my iMac with Windows 7. Is there a way to remotely login to the Windows 7 virtual machine that is running on my iMac with my Macbook Air?
