bzr info tells you when you are out of date - when update is needed.

Why do you unbind and bind? When you are offline you can just do 'bzr
commit --local'.

You can just put 'bzr update' in cron - when there is nothing to do,
nothing will happen.

I'm -1 on this concept: When we put bound branches into the mainline, it
was considered that having yet *more* local state to track was not a
good thing - thats why there is --local options to some commands, to
allow you do perform offline work without losing what branch you are
bound to.
