Has anyone successfully configured push notification services?

I have been struggling with this since mid December and still have not figured out how to configure or even debug push notificaiton services. I am running a Mac Mini Lion Server and have read every thread, article, snippet and breadcrumb on these discussion forums and elsewhere. I have been through jabberd/twisted/SSL/config in fine grained detail.

So my question is simply - is there anyone out there that has 10.7.3 and Push Notifications configured for mail/Calendar Server/iChat working? Did it just work out of the box for you by checking the box and requesting a cert? Did you have to go through a detailed debugging exercise and if so, what are the key components in this spaghetti that is the Lion APNS gateway?

I am happy to start posting logs and working with some contributors on this, but I would like to know that it is even possible before investing the time.

HELLLLLLLP! Please tell me there is light at the end of this tunnel!
