In theory yes... but an alarm clock going off a minute too late doesn't really
look good. If we can do it better we should...

I'm not sure if poweroff is really necessary... it would be cool if it is
possible but i suppose we could live without this if it is complicated to implement.

Definitely...

Well... usually applications will use both an alarm signal and some notification
on screen. If the alarm signal is disabled by a system state and no user input
received the device should just go to sleep again. Some system message
indicating a missed alarm if the evice state is changed might be another
possible way to deal with this.

Would be useful - in particular for gpe-calendar :-)

Well... your summary would be a good start for a wiki page :-)
