I presented at the Twin Cities Connected Systems User Group last night on the Managed Services Engine. You can get the presentation here.
The Managed Services Engine is a CTP technology that acts as a service intermediary. It helps abstract consumers form the services that they call, performing things such as xslt mapping, protocol switching, version mapping and service stubbing (useful for testing unhappy service respone paths as well as development of the consumer before the service is really ready.)
