MS Office Communicator Has My Implementation of DO NOT DISTURB

Although I can't seem to locate it, I am sure I wrote on my prior blog, about my idea for a DO NOT DISTURB mode on cell phones. Well I just discovered that Office Communicator (IM client) has the implementation I had in mind. If you try to send a message to someone who has set themselves to DO NOT DISTURB, you get a warning, pointing out they are in DO NOT DISTURB mode, and asking if you really want to proceed to disturb them. Very nice.
