Good question - I've heard this discussed as part of the notification 
area of Lemonade, and I'd got it into my head that we were talking 
about a simple icon or blinking light - very much a boolean 
indicator, rather than a numeric display.

Well, I'd really seen this as a protocol to avoid synchronizing - 
what various people have described as "true push". A "sync needed" 
protocol is really a lot simpler, and simple STATUS message packaging 
probably do for that and the MWI scenario very nicely.

I'd also state for the record that I don't think we need more than a 
STATUS response, but pushing content and detailed state out of band 
has been a consistent feature of many proposals.

I'm not so sure. I think the first two can be seen as the limits on a 
spectrum of machine-readable notifications, whereas machine 
readability isn't nearly so important when considering a 
user-directed alert.

Luckily, I also happen to think that user-alerts are essentially 
taken care of by Sieve, on delivery.
