I do this every few months, to remind myself how badly OS X screen sharing sucks.
Yeah, I'm on Leopard, but from all I read Snow Leopard takes OS X remote control from extremely lousy to really lousy.
It's painful for a Mac user to remember that Microsoft Remote Desktop Services (similar to Citrix remote desktop) is about ten years old.
Microsoft (Citrix?) used to have some serious skills.
Update: Speaking of Apple senescence, I remember when the OS could 'remember' the location of files stored on a server and mount the server on demand. Now if I click a shortcut to a network folder I get "A volume failed to mount". Once upon a time I'd get a login.
That capability was lost in the last few years of OS X development, one of several dumbing-down changes to the OS.
