How to go about developing and deploying an SCEP/MDM infrastructure for the Enterprise iOS program

I am trying to use the new OTA enrollment and device management capabilities in iOS 4 to provide wireless app distribution for the enterprise. So far, I have come across a lot of third party MDM providers that seem to charge by the device. I don't believe this is something very hard to do on our own, especially as a prototype.

My search has led me to some open source software for SCEP. Together with the OTA configuration reference from Apple, I want to believe that the next step would be to actually implement an MDM server. Now, the WWDC talk had slides on various MDM queries supported by iOS 4, including installing and removing provisioning profiles, but there's no reference implement开发者_如何学Cation or even exposed API that I could find.

Does anyone have any experience trying to fully develop an enterprise distribution and management system without third party software?

MDM providers that I've seen are acting as SCEP proxies so that you don't have to expose your certificate server to the internet.

The best open source SCEP server I've found so far is Dogtag (http://pki.fedoraproject.org/wiki/PKI_Main_Page)

woops I was meaning to comment.. not answer.
