Can we develop a phone that can show status of persons in contact list. Messenger service can show people in your contact list (this case would be phone book in cell phones) current status i.e. away, busy etc. there is also the option of posting a note. A cell phone should be able to operate much in the same way. I must pick up my cell phone and be able to post a note (eg I am in a meeting) and set my status to busy so any one who has my number in their phone book can see me as busy when they scroll through, so they'll know not to call if they were hoping to do so and visa versa
