I was just wondering the same thing... Previously i somehow managed to get MSN change to my personlized status when idling - this seems to be impossible in the live version.
If the author is reading this - please implement this feature!
It would be very convinient for my business to set an autoreply that they should try send email instead, when we are away. But it's very annoying to change to this status manually, before leaving the computer.
