The simplest way to transform an in-proc COM server into an out-proc COM server is creating a COM+ application. What are the possible drawbacks of doing it this way?

Check.

He's merely telling us that they have used C++ and COM in the implementation of the runtime.

Many COM objects contain embedded typelibs in the resource section of the executable.
You may, as weismat says, inspect the TLB files.
Exports are DllGetClassObject, DllRegisterServer, etc (for DLL-hosted COM).
