Nice idea, but...

It does what it said but there are a couple of concerns. Using location silent is not practical as it will eat your battery in no time at all. The calendar option is a bit flakey. If you is the silent switch it will still make the phone ring at the end of a meeting.
Essentially a very nice idea but it needs to have a simple scheduler added to setup regular silent times.
