In Josh's blog post about "Stump the PRO" - he mentions WMI & ConfigMgr. I wanted to post a bit more context for everyone interested in that integration point.
Overview: ConfigMgr client agent uses WMI to query AMT via the HECI driver.
The Configuration Manager client agent ships with a new WMI provider for the AMT HECI driver. Additionally, we have extended the SMS_DEF.MOF file with new classes that support the WMI provider. This is used by the hardware inventory agent when returning information about the client computer. You'll find the data easily for your AMT computers using the resource explorer for an AMT computer. The information is categorized under a new resource called "AMT Agent"
The inventory from that agent make a great basis for building queries to use the in-band agent based provisioning method.
