IMO, one of the ways through which this can be done is to create a normal COM Dll as per the method you mentioned in the link and then after registering your COM dll, change it to a surrogate DLL. This can be done very easily through OLEView utility, although you can do it manually as well by changing registry entries as well through the method mentioned at http://msdn.microsoft.com/en-us/library/ms686606(VS.85).aspx.

By making this a surrogate DLL, it will run in it's own dllhost.exe and hence will be out-of-process.
