Could Websockets or http://en.wikipedia.org/wiki/Comet_(programming) be
of help here?
For CalDAV and CardDAV we (Apple, http://calendarserver.org) have used XMPP
pubsub and our own APNS to implement a push notification service. Frankly I
think the IETF should have developed a proper notification protocol for use
alongside other protocols a long time ago - simply "blessing" XMPP pubsub
as the solution for that would be fine from a standards point, but perhaps
something else (new) coukld be done too. What then needs to be defined are
the hooks in each underlying protocol to allow clients to discover the
appropriate pubsub service. In CalDAV/CardDAV that is simply done using
WebDAV properties to advertise the essential client push configuration.
So, in my opinion, whilst push notifications should be a requirement for
imap5, we should not define that protocol and instead push the IETF to
provide such a protocol for general use.
