Alarmoid ($) will auto-quiet the phone at the times you specify, but it will also allow folks you pinpoint to get thru. I created a "VIPs" group at my google contacts website, then told Alarmoid to let those folks thru no matter what. Very easy to set up, as it's a one-trick pony. but it performs that trick exceedingly well! Bonus: widget allowing easy/quick shut-up-now for xx minutes/hours.
