I've been threatening to build/working on an LC push server library, but
it's on the back burner, right now, and probably will be until the end of
the year, at the earliest.
• First, go to, and add yourself to the cc list for
bug 10901 and 18692.  Those are for various improvements in push support
that will allow us to do things like silent push (push data to your app
without your app having to do it while it is running, wasting the user's
• The piece that leaves the most to the imagination is handling the id
reporting from the devices.  On iOS, the only way to pull an app's push id
on a device is inside of the app.  So your app has to report its id to your
server, somehow.  "Somehow" can be a file drop (e.g. dropbox, since we talk
about that service a lot), a special port or URL, a web db query, etc.
• Your app checks to see if it has already reported its push id.  If it has
not, it reports it (however, there isn't any harm in reporting it each time
it launches).
• Perhaps your server implements a mechanism to notify your app that the
push id was received (e.g. by sending a push notification back), so that
the app does not notify the server, again, for this push id
• If your app notices that its push id has changed, it reports the old id
and the new id (or if you have some other way of keeping track of a
particular install on a particular device, you could report that with the
new id, instead).
• Check, periodically, to see if the push server is reporting that some id
or another is no longer active and should be taken out of service (I have
never received such a report, but you are supposed to do this, anyway).

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
